I just checked with my dad if he remembered these when he worked at Philips. And he did. He said the music/re-creations on them were made at the old Soundpush Studio. The musicians were the session players. He told me they didn't use any of the Philips session players, because it would have cost to much. As for the master tapes. Those are long gone. He said anything recorded for this music format was never kept and they just reused the tapes. My dad added that one of the producers of these was still alive and wanted to know if you would be interested in his email? As he worked with this format for nearly 15 years. Let me know.

Techmoan, the speaker output of this device is for a high voltage speaker system and is used to be able to drive several speakers using a step up transformer in the amplifier and step-down transformers at each speaker. This is akin to a high-voltage power distribution. Typically the US uses 70V while in Europe 100V are more common. These distribution systems have a much higher impedance than a normal speaker (4-8 ohms) and your adapter likely has an input impedance that is around that figure so it is likely that the low volume you are currently getting is simply due to an impedence mismatch. Here's a wikipedia article describing these systems: en.wikipedia.org/wiki/Constant-voltage_speaker_system
@@piketfencecartel I was hoping somebody posted something along these lines as well! I used to work for a distributor of Viking, Valcom, and Bogen equipment and have designed many a system around 70v stuff!
@@piketfencecartel Most of the things I scoped out and designed were Grocery stores and Warehouses. Heck I still get the Viking catalog in the mail and have not worked with them in a few years.

You and Colin from TDNC are getting really good with the repairs of this vintage electronic equipment. I understand it's out of necessity to create the content and share with us, just wanted to note the time and effort put into these vids.
I repaired a vintage soundstream reference class a amp then traded it for a pair of old school audiobahn 10" subwoofers and I had to repair the foam surround on one when I leaned over it with a screwdriver and poked a hole in it... What a great time to live in.
I've given various fragmented responses on the actual meaning of the type number format (Large Giant Cassette etc.) used for those machines, but it might be more convenient to put it all in one post. The letters are more or less of a coincidence, so Philips never intended any useful meaning for them. Up to the mid 1960's model numbers with EL were used for "ELectro Acoustic equipment" (some survived longer, but new numbers were assigned using the new system by 1967). Starting from 1963, Philips prepared for computerising all of their operations toroughly and assigned 12 digit code numbers to everything and their mother. Internally, such code numbers were also used as SKU's for completed equipment, so replacing normal type numbers. Since such numbers are hard to remember and would probably be bad for sales, even of professional equipment, every division made their own system to map them to useful model numbers. The electro acoustics division used a system starting with an arbitrary L representing "their" first two digits, followed by two letters derived from the numbers using a translation key, then up to 6 digits directly taken from the code number and 3 internal use only which weren't reflected in the normal type number. This was done as follows (according to 1967 information, new numbers were added when necessary): LGB0.../.. through LGG9.../.. = Functional Music LGB0 = original recordings on tape LGB2 = production tapes LGB4 = programs on tape LGB6 = original recordings with splices LGB8 = production tapes with splices LGC1 = programs with splices on tape LGC2 = equipment for functional music LGD0 = Germany Don't ask me what all of this means exactly, as I don't have much specific FuMu/BGM knowledge. Splices might mean "something spliced in between music"? In Dutch it just says "met tussenlassen".
@@firesurfer I well remember broadcasting on hospital radio in the early 70s, watching the splices going through the read heads on the tape deck as the jingles played and praying they would hold! No Spotmaster carts for us...
I can't get that song from the end of the video out of my head now. It's worse than the "interlude" music from Monty Python and the Holy Grail! Great video! Background music media is one of my favorite subjects.
That is the first time anyone ever said that about a Philips tape deck. Anything they did since early 1960s was very cheap. The more plastic the worse repair ability along with it.

A master who is appreciated in many ways, by many parties, with many interests. Thank you!
I love it when I need to take something out, but then it turns out I need to take something else out first, and then I have to actually disassemble the other part first and that's when I know I am going to have a screw left over.
I love the build quality of the newer machine. All metal, everything is thought through, like the through-hole for the screwdriver and the flex brackets for the circuit board. And it's made to be disassembled, cleaned and maintained. I wish this was a more common practice.
More of a fan of the older one, myself - love the wood cabinet. Unfortunately, if this thing cost a small fortune in 1970, you can imagine that it would cost a large fortune to completely hand build them in 2021... which is why we have miniaturized, mass produced electronics with surface mount components that the unwashed masses can actually afford :)
@@iroll You can still buy entirely-IC units shoved into high-end cabinetry. Doesn't make sense to me, personally, but, hey to each their own. I prefer "my phone can now play pretty much anything" instead.
@@PongoXBongo I also meant hand assembling/soldering the components, in a time when real wages for manufacturing were as high or higher than they are now, and let's not forget all those discrete components that would cost 10 to 100x what the comparable components would cost now. Just like it was back then, a unit like this would cost a mint to make now... which is why we prefer our phones :)
I think part of the point OP is making is how it is designed to be repaired. There could have been an equal to that for modern devices where the designers give an easy and definite way to replace components which go out the most often. But instead, companies prefer to pursue maximum profit by designing systems and paying lawyers to ensure that every device we use today gets thrown in a landfill where it poisons our planet for years and force the end user to buy a whole new device whenever anything goes wrong.
@@Woogoo336 I totally agree with "right to repair" and like to tinker with things myself (can still pay or ditch afterward). . Things that are meant to be servicable remind mr of desktop PCs, versus nonservicable laptop PCs. Great for those that know what they're doing, but also larger and more intimidating for those who don't.
I would love to see some of these devices and obscure formats in person. I really wish that Techmoan would open a museum. Would anybody else visit a Techmoan Museum?
My Dad was like a modern-day Apple fanatic in terms of brand loyalty. He firmly believed that Philips stereo systems were superior to most anything else in the market.

So I watch this content in his memory and it helps me to remember happy times. Hanging out with Dad while he tinkered in his garage/workshop, surrounded by car parts, oscillators, old radios and all sorts of tech, old and new.
Grease-removing chemicals actually won't help in cleaning this stuff, as they're usually alkali-based. What you need is strong organic solvents like ethylene chloride or dichloromethane, which are main components of paint removers.
Don't waste your time with so called degreasers or cleaners. Almost every glue or grease imaginable is easily removed with either Acetone or Mineral Spirits.
There's something magical about the numerous phyla, orders, and families of old tech from the whole swathe of the 20th century, as they they emerged, mutated, and (often) went extinct.
Great work! I love seeing what old gear was like inside. What is immediately impressive to me is that this old gear was designed to be taken apart and repaired. The circuit board that folds away to gie access to that place, the clips and screws to remove parts, and right down to an allen screw on the belt spindle!! I mean, designers gave consideration to repair! Unheard of nowadays!

Wow! Didn't fully appreciate the size until you showed the tape next to a videocassette! Many thanks for this Mat. If there's any format oddity that's ever existed, I know you'll track it down eventually!

What a great documentary. The coolest thing was that finally after all the talking the thing worked and Tech Moan was completely silent. Probably shedding a tear. 10 out of 10 this one.
The low volume level is most probably not caused by components but mismatch with output of the unit and the speakers you connected. It's meant to work with 100V speaker system used in large installations, where you can run many speakers over long distances, e.g. in a shopping mall. This require a transformer in the speaker to match the impedance and levels.
Exactly what I came here to say. This isn't just a tape player, it's also a PA amp for a distributed speaker system. Google 70v to 8ohn transformer and you can use that to drive a conventional speaker, and as long as the amp is ok, it should sound fine.
Exactly. Commercial PA installations use 70V or 100V speaker lines. Benefits are: smaller wire gauge, longer distances and more speakers on the same branch. Look at Bose industrial speakers and you will see the 100V option being available to purchase.
But it had a 10V setting and he used it so its not meant for just 100V speakers, I agree there is a mismatch and a good chance there are some dodgy Caps, shame !
@@jonglass Wrong type of transformer, the one he used is to take speaker level outputs and drop them down to line level. What Peter said above is the way to go.
@@nilswegner2881 look up "The Joy of Painting", which is the PBS series where Bob Ross would show off his version of the wet-on-wet oil painting technique. If you want to watch some example episodes, they tend to replay a couple seasons every weekend on www.twitch.tv/bobross with the permission of the current rights holders. This weekend they seem to be rebroadcasting seasons 23-26 of "The Joy of Painting". (Don't take the "it's ruined!" and similar criticism in the chat as genuine remarks; it's mostly meme commentary that has developed in the community that rewatches the episodes just about every weekend.)
@@FiXato it is also available here on TH-cam, they also uploaded the 1 hour special episode that's NEVER been aired on US TV. I also never been heard about Bob Ross (because I'm in the Philippines, and I was only a year old when the final episode has been aired) until his special episode persistently showing up on my "up next" feed (especially when I watch ASMR videos) here on TH-cam.
Watching your videos makes me thankful with how good we have it these days. I did not have many toys as a child. Television was my main source for entertainment along with the original Nintendo Entertainment system. So I guess I had it pretty good back then as well.
I found one of these in a cupboard at the Amsterdam Concertgebouw when I worked there a few years ago. I asked about it because at first I thought it was a video recorder. As you'd expect, it was used to pipe background music around the building. When I looked for a tape to check whether the machine still worked, I was told that they had all been sent back to Philips. The subscription system gave them fresh tapes every 6 months provided the old ones were returned.
I've seen the word "large" abbreviated as "lg." before, so perhaps lg in the model number stood for "large" Philips cassette player? To differentiate it from the "compact" Philips cassette player? Just a thought... Good on you getting this thing working. I love stuff like this -- you'll never see it on any other channel on TH-cam, that's for sure. Thanks! :-)
Unfortunately not, but good thinking anyways. The L stood for "ELA division" (electro acoustic products in the widest sense of the word, also including video and education). The GC2 stood for the business group and category of equipment and was chosen somewhat arbitrarily (actually every piece of equipment got a hierarchical commercial number, SKU in modern language, which was used to designate the equipment and then the letters were derived from it to form a more human readable model number).
@@koppadasao no it doesn't. If you're just taking a guess, you shouldn't write it as if it was an authoritive answer. On the other hand, it would have been nice if B was for Band (dutch) and C was for Corder (english) etc. Maybe in an alternate universe.
Yet again another fantastic video from Techmoan. Just a tip, when taking things apart, take photos on your phone or digital camera, it avoids “it’s upside down” moments😀. Seriously, it’s great to see the Philips electronics of years past, they seemed to have a distinct style. Grundig had the same style to their electronics. Great that you got it working.
Nice that your subscriber counter goes up from 1.14M to 1.15M during the time this video took to make! Long may it continue increasing! PS: Little tip about desoldering anything, especially old stuff like this: Flood the joint with new solder and even use a flux pen to get the old solder really fluid before removing it. Might have even been able to save that PCB pad :-))
It's awesome to see you getting more comfortable with repairing stuff like this :) If I may offer a couple of tips: Capacitors can't really be measured accurately when they're in-circuit. Not that it mattered in this case, since they clearly needed replacement since they physically leaked. Also, your de-soldering pump was set WAY too high, like 100 degrees too high, and this is probably why the trace on the PCB lifted. It's all part of the learning process.
That music takes me instantly back to an airy, modern shopping centre in Sydney called Roselands in the late 60s, when we all used to get dressed properly to go shopping and it was slightly glamorous. :-)
That summary at the end is a bit sad, really. There are who knows how many thousands upon thousands of hours of dedicated artistic work which will most probably never be heard again, not because of it being lost but rather because it's in essence been locked away for eternity. I mean who knows how much of this sort of stuff has been truly lost already as masters of incredibly obscure esoteric things have swapped hands with rights holders etc etc and what's slipped through the cracks. That said the repair and machine were really interesting. I'm remembering I think a few years ago or whenever watching a video in which Techmoan was saying something about not doing any in-depth repairs... and yet here he is whipping out the soldering iron, disassembling a good portion of the machine, etc. :D
As session musicians working on "beautiful music" covers of pop songs for shoppers, I'm sure they felt no attachment to these recordings other than income they provided.
Nina Paley went through an amazing amount of hassles (and something like $70K, I think), to use music from the 1920s & '30s (Annette Hanshaw), which was "owned" by Sony -- As far as I know, Sony just had this stuff locked up somewhere with no plans to ever release it, but they still made it very difficult for someone else to use it -- The music probably would just have been mostly unknown if Paley hadn't gone through the effort to put it in her movie (which you can watch for free online).

1:53 Having handled compact cassettes all my childhood, this scene really messes up my head when the incredibly tiny hands enter the picture to grab the regular size c-cassette.
I am happy to see the machine from Denmark found it’s way to you Mat. I saw it on sale and would have bought it as I thought of Techmoan right away, but of course it was all ready sold when I got around to bid on it myself. Thanks for great content!
The compact cassette was earlier (1963). But you are not too far from the truth, there were other cassette systems before, and yes those were mostly larger.
That was an awesome repair! The coolest thing I feel is that music hasn't been heard in this format on this equipment in decades. Thanks for bringing it back!
Man, wish I could get a copy of the music on that tape. I love old department store music. Used to have a laptop that would quietly play muzak whenever the lock screen came on from being idle. People would always get confused and look around trying to figure out where the goofy music was suddenly coming from.
You are a super hero for all technology! You are preserving pieces of technological history. Thank you for another great video. My mind always imagines the times when this was used, and people of those times. It's like looking at old photos, except with our ears.
I tell you what I really do enjoy when your able to make these old machines work. I would love to hear more tapes. I love listening to unmarked tapes. The mystery and time captured by these.
Still amazed how as soon as you put some obscure piece of music up on youtube licensors come out of the woodwork. There's this Japanese record that's been out of print for over 20 years and routinely goes for over ¥10000 on yahoo auctions, and yet a video of it up on youtube got content matched almost immediately. You'd think if they cared so much to take this stuff down they'd care enough to distribute the stuff somehow, like Seeburg eventually did.
I'm amazed people are amazed by that, at this point every label company will have its every piece of music digitised and put in the content match database, everything else is fully automatic, it has nothing to do with whatever they care or not, it's just free money for them.
1万 isn't much for something that's been out of print for so long especially if the record actually plays correctly. If you're worried about preservation uploading to youtube isn't the right way to go about things. They don't have people going around taking stuff down just to be mean. It's all automatic.
For the line out you can piggyback with wires plugged into the DIN holes. As for the desoldering iron, not sure it was to be used on caps with long tabs. I'd go large regular iron,wick and unfold the hot tab's with pliers. Now, congrats for the fixing!!! Love your channel a lot!!!
Absorbing stuff... eventually an easy fix, but stil, obtaining the unit, having it shipped and taking the time to review it, that's great! Looking back at the way things were made, the longevity of their function (apart from the petroleum jelly based belts of course)... good old days. Thanks for this!
'Philips Functional Music’ was a service by Philips in the ’70’s on 6″ tapes and it is the start of why Philips CD-i is compatible with Background Music CD’s (BGM).
Amazing well done Techmoan. I think the output to the speakers in 100v if selected, line level . Common with pa speakers and would need a transformer to couple with the speaker . This will enable no voltage loss and little noise pick up . Also you could series up separate speakers in the system each one having a transformer on the speaker connected👍
@@russellhltn1396 yes but what they use to do was separate the output transformer from the power amp and run cables to it so that the resistance of the cable was no longer an issue that allows you to reduce the resistance of the cable running the speaker because you are running a higher voltage. Then the speaker has the output transformer as well as the speaker . If you look on eBay eagle international made these transformers back in the day. Just makes the output stage efficient to run long cables to speakers
It's just incredible to think about this device. So much R&D, the salesman taking it to wherever it spent it's working life, just hundreds of people lived with and worked on this device... and not even a century later we aren't even fully aware of what it was named. We wouldn't have known it existed had one of the machines that played it had not been found on ebay.

That was a LOT of work, Matt. Thank you for putting in the time and effort to get that relic working again. I really wish there were better Fair Use laws which allowed YTers such as yourself to play clips of whatever, say no more than 1 minute duration, for the purposes of demonstration. Really sad how these lawyers and corporations have put a clamp down on things. Still, the machine itself was interesting enough. Again, thank you.
As always I love seeing these more 'industrial' types of equipment. Fantastic that you were able to get the system up and working. I bet it was a fun few hours exploring that tape!
YOU MAKE IT !!! you did it !! You gave life to something who is PART of History !!! Bless you Techmoan!! Im really suprised of your TALENT and AMAZING gifts !!!
Matt, given all the repairs you do on exceedingly rare equipment, you really deserve better screwdrivers! Especially with slotted screws, a) matching the driver size is critical, and b) top quality drivers have parallel-blade slotted drivers that don’t damage the slot. (My recommendation is PB Swiss. They’re not cheap, but they’re not exorbitant either, and I have yet to find a superior screwdriver. Their tip precision is just insane.)
What a fascinating, thrilling video! Wonderful seeing how much work went into designing and building these machines and how great was it when the music started playing!
We have a product here in the USA called "Goo Gone" which is citrus based and always seems to work for me on gooey/sticky stuff off of whatever you've got. I recommend trying it next time you need to remove something gooey like that rubbery mess.
Brilliant, as always. Getting my belt-turned-to-gunk thrills vicariously these days. I wonder if Philips themselves could shed any light on this format?
Yes, Ive just previously watched a My Mate Vince video, on the restoration of an early 80's Roberts boombox, with the remains of belts in a similar condition!
As always I enjoyed this video I like the fact that you don't go into technical details like IPS or RPM just down to earth repair and diagnoses that you do
I suspect that the voltage setting is for an directly powered speaker and the resultant audio signal will be centered at 10V instead of 0V. You would need an inline capacitor or some other DC bias removal circuit to remove that DC offset, and that should make the audio louder and clearer. Worth a try :) Great video.
The voltage level is a nominal level of the audio output, not a DC bias. Higher voltages run lower current and can support longer runs of wire - which is important in malls or other large areas where nobody wants to pay for leagues of thick cabling. A transformer on each end converts the low-voltage AC to high voltage, then back to low voltage at the speaker.

Techmoan, the speaker output of this device is for a high voltage speaker system and is used to be able to drive several speakers using a step up transformer in the amplifier and step-down transformers at each speaker. This is akin to a high-voltage power distribution. Typically the US uses 70V while in Europe 100V are more common. These distribution systems have a much higher impedance than a normal speaker (4-8 ohms) and your adapter likely has an input impedance that is around that figure so it is likely that the low volume you are currently getting is simply due to an impedence mismatch. Here's a wikipedia article describing these systems: en.wikipedia.org/wiki/Constant-voltage_speaker_system

Since such numbers are hard to remember and would probably be bad for sales, even of professional equipment, every division made their own system to map them to useful model numbers. The electro acoustics division used a system starting with an arbitrary L representing "their" first two digits, followed by two letters derived from the numbers using a translation key, then up to 6 digits directly taken from the code number and 3 internal use only which weren't reflected in the normal type number. This was done as follows (according to 1967 information, new numbers were added when necessary):
LGB0.../.. through LGG9.../.. = Functional Music
LGB0 = original recordings on tape
LGB2 = production tapes
LGB4 = programs on tape
LGB6 = original recordings with splices
LGB8 = production tapes with splices
LGC1 = programs with splices on tape
LGC2 = equipment for functional music
LGD0 = Germany
Don't ask me what all of this means exactly, as I don't have much specific FuMu/BGM knowledge. Splices might mean "something spliced in between music"? In Dutch it just says "met tussenlassen".
"I opted for the LGBT version, but you do you"
th-cam.com/video/--1lSmtuyUg/w-d-xo.html
Most likely custom ordered tapes with sale advertisments and such stuff cut in between the music..
At this time splices were physical. In order to add or delete something you cut out or added physical pieces of tape.
@@firesurfer I well remember broadcasting on hospital radio in the early 70s, watching the splices going through the read heads on the tape deck as the jingles played and praying they would hold! No Spotmaster carts for us...
I can't get that song from the end of the video out of my head now. It's worse than the "interlude" music from Monty Python and the Holy Grail!
Great video! Background music media is one of my favorite subjects.
Techmoan started my intrest in BGM for me too.
The engineering on that thing is amazing. So much metal, everything screwed in, user serviceable, truly build to last.
Except for all the shit that didn't last
That is the first time anyone ever said that about a Philips tape deck. Anything they did since early 1960s was very cheap. The more plastic the worse repair ability along with it.
The ever increasing amount of black goo stuck to his hands while progressing into the video perfectly demonstrates the rabbit hole he went in.

A master who is appreciated in many ways, by many parties, with many interests. Thank you!
the music has fallout vibes like crazy. it makes me think all those tapes of "elevator music" are gone
I love it when I need to take something out, but then it turns out I need to take something else out first, and then I have to actually disassemble the other part first and that's when I know I am going to have a screw left over.
I love the build quality of the newer machine. All metal, everything is thought through, like the through-hole for the screwdriver and the flex brackets for the circuit board. And it's made to be disassembled, cleaned and maintained. I wish this was a more common practice.
More of a fan of the older one, myself - love the wood cabinet. Unfortunately, if this thing cost a small fortune in 1970, you can imagine that it would cost a large fortune to completely hand build them in 2021... which is why we have miniaturized, mass produced electronics with surface mount components that the unwashed masses can actually afford :)
@@iroll You can still buy entirely-IC units shoved into high-end cabinetry. Doesn't make sense to me, personally, but, hey to each their own. I prefer "my phone can now play pretty much anything" instead.
@@PongoXBongo I also meant hand assembling/soldering the components, in a time when real wages for manufacturing were as high or higher than they are now, and let's not forget all those discrete components that would cost 10 to 100x what the comparable components would cost now. Just like it was back then, a unit like this would cost a mint to make now... which is why we prefer our phones :)
I think part of the point OP is making is how it is designed to be repaired. There could have been an equal to that for modern devices where the designers give an easy and definite way to replace components which go out the most often. But instead, companies prefer to pursue maximum profit by designing systems and paying lawyers to ensure that every device we use today gets thrown in a landfill where it poisons our planet for years and force the end user to buy a whole new device whenever anything goes wrong.

I would love to see some of these devices and obscure formats in person. I really wish that Techmoan would open a museum. Would anybody else visit a Techmoan Museum?
I'd fly from the US to the UK to see it!
Perhaps at the Science and Industry Museum in Manchester - which I think...is a city that Techmoan is near.

Grease-removing chemicals actually won't help in cleaning this stuff, as they're usually alkali-based. What you need is strong organic solvents like ethylene chloride or dichloromethane, which are main components of paint removers.
Don't waste your time with so called degreasers or cleaners. Almost every glue or grease imaginable is easily removed with either Acetone or Mineral Spirits.

The circuit board that folds away to gie access to that place, the clips and screws to remove parts, and right down to an allen screw on the belt spindle!! I mean, designers gave consideration to repair! Unheard of nowadays!

I thought all these cassettes were destroyed by a giant meteorite, back in the day.
That, was a delightful description.
What a great documentary. The coolest thing was that finally after all the talking the thing worked and Tech Moan was completely silent. Probably shedding a tear. 10 out of 10 this one.
thank you for not taking the shortcut, watching you mend these machines gives me a lot of satisfaction to see, awesome
The low volume level is most probably not caused by components but mismatch with output of the unit and the speakers you connected. It's meant to work with 100V speaker system used in large installations, where you can run many speakers over long distances, e.g. in a shopping mall. This require a transformer in the speaker to match the impedance and levels.
Exactly what I came here to say. This isn't just a tape player, it's also a PA amp for a distributed speaker system. Google 70v to 8ohn transformer and you can use that to drive a conventional speaker, and as long as the amp is ok, it should sound fine.
Exactly. Commercial PA installations use 70V or 100V speaker lines. Benefits are: smaller wire gauge, longer distances and more speakers on the same branch. Look at Bose industrial speakers and you will see the 100V option being available to purchase.
But it had a 10V setting and he used it so its not meant for just 100V speakers, I agree there is a mismatch and a good chance there are some dodgy Caps, shame !
He had a transformer in the mix. 8:12
@@jonglass Wrong type of transformer, the one he used is to take speaker level outputs and drop them down to line level. What Peter said above is the way to go.

Watching your videos makes me thankful with how good we have it these days. I did not have many toys as a child. Television was my main source for entertainment along with the original Nintendo Entertainment system. So I guess I had it pretty good back then as well.
I found one of these in a cupboard at the Amsterdam Concertgebouw when I worked there a few years ago. I asked about it because at first I thought it was a video recorder. As you'd expect, it was used to pipe background music around the building. When I looked for a tape to check whether the machine still worked, I was told that they had all been sent back to Philips. The subscription system gave them fresh tapes every 6 months provided the old ones were returned.
The lengths you went to to listen to this tape are commendable. As always, a highly entertaining video!
I've seen the word "large" abbreviated as "lg." before, so perhaps lg in the model number stood for "large" Philips cassette player? To differentiate it from the "compact" Philips cassette player? Just a thought...
Good on you getting this thing working. I love stuff like this -- you'll never see it on any other channel on TH-cam, that's for sure. Thanks! :-)
damn I should have scrolled down a bit before commenting I was thinking the same thing.
LG is Dutch, not an abbreviation for the English word 'large'
Anyway, the B in LGB stands for 'band', Dutch for tape
Unfortunately not, but good thinking anyways. The L stood for "ELA division" (electro acoustic products in the widest sense of the word, also including video and education). The GC2 stood for the business group and category of equipment and was chosen somewhat arbitrarily (actually every piece of equipment got a hierarchical commercial number, SKU in modern language, which was used to designate the equipment and then the letters were derived from it to form a more human readable model number).
@@koppadasao no it doesn't. If you're just taking a guess, you shouldn't write it as if it was an authoritive answer. On the other hand, it would have been nice if B was for Band (dutch) and C was for Corder (english) etc. Maybe in an alternate universe.

“I’m really into functional music”. Can’t get more obscure than that 😂

Hmm, people music. I like it!
I'm sticking with object-oriented music thank-you very much.
He should have just said Muzak really. lol
Yet again another fantastic video from Techmoan. Just a tip, when taking things apart, take photos on your phone or digital camera, it avoids “it’s upside down” moments😀. Seriously, it’s great to see the Philips electronics of years past, they seemed to have a distinct style. Grundig had the same style to their electronics. Great that you got it working.
Nice that your subscriber counter goes up from 1.14M to 1.15M during the time this video took to make! Long may it continue increasing!
PS: Little tip about desoldering anything, especially old stuff like this: Flood the joint with new solder and even use a flux pen to get the old solder really fluid before removing it. Might have even been able to save that PCB pad :-))
Don't give him soldering tips. He doesn't appreciate it.
It's awesome to see you getting more comfortable with repairing stuff like this :)
If I may offer a couple of tips:
Capacitors can't really be measured accurately when they're in-circuit. Not that it mattered in this case, since they clearly needed replacement since they physically leaked. Also, your de-soldering pump was set WAY too high, like 100 degrees too high, and this is probably why the trace on the PCB lifted. It's all part of the learning process.
That music takes me instantly back to an airy, modern shopping centre in Sydney called Roselands in the late 60s, when we all used to get dressed properly to go shopping and it was slightly glamorous. :-)

That summary at the end is a bit sad, really. There are who knows how many thousands upon thousands of hours of dedicated artistic work which will most probably never be heard again, not because of it being lost but rather because it's in essence been locked away for eternity. I mean who knows how much of this sort of stuff has been truly lost already as masters of incredibly obscure esoteric things have swapped hands with rights holders etc etc and what's slipped through the cracks.
That said the repair and machine were really interesting. I'm remembering I think a few years ago or whenever watching a video in which Techmoan was saying something about not doing any in-depth repairs... and yet here he is whipping out the soldering iron, disassembling a good portion of the machine, etc. :D
There are also examples of lost master tapes, for example, some of the LEGO Island master tapes were lost in a houseboat accident
As session musicians working on "beautiful music" covers of pop songs for shoppers, I'm sure they felt no attachment to these recordings other than income they provided.
Nina Paley went through an amazing amount of hassles (and something like $70K, I think), to use music from the 1920s & '30s (Annette Hanshaw), which was "owned" by Sony -- As far as I know, Sony just had this stuff locked up somewhere with no plans to ever release it, but they still made it very difficult for someone else to use it -- The music probably would just have been mostly unknown if Paley hadn't gone through the effort to put it in her movie (which you can watch for free online).

What a great job! My husband is a repair tech...we were both fascinated. Good on you for sticking with it to the end!
I always wondered why Philips called it the COMPACT cassette. I guess it was to differentiate it from the LARGE GIANT cassette.
The compact cassette was earlier (1963). But you are not too far from the truth, there were other cassette systems before, and yes those were mostly larger.
What a wonderful sense of achievement , it really cheered me up to hear that machine working after following your repairs

I tell you what I really do enjoy when your able to make these old machines work. I would love to hear more tapes. I love listening to unmarked tapes. The mystery and time captured by these.
Still amazed how as soon as you put some obscure piece of music up on youtube licensors come out of the woodwork. There's this Japanese record that's been out of print for over 20 years and routinely goes for over ¥10000 on yahoo auctions, and yet a video of it up on youtube got content matched almost immediately. You'd think if they cared so much to take this stuff down they'd care enough to distribute the stuff somehow, like Seeburg eventually did.
All TH-cam really care about is making money from it in some way. If they can't make money, they won't allow it.
I'm amazed people are amazed by that, at this point every label company will have its every piece of music digitised and put in the content match database, everything else is fully automatic, it has nothing to do with whatever they care or not, it's just free money for them.
1万 isn't much for something that's been out of print for so long especially if the record actually plays correctly.
If you're worried about preservation uploading to youtube isn't the right way to go about things. They don't have people going around taking stuff down just to be mean. It's all automatic.

'Philips Functional Music’ was a service by Philips in the ’70’s on 6″ tapes and it is the start of why Philips CD-i is compatible with Background Music CD’s (BGM).
Amazing well done Techmoan.
I think the output to the speakers in 100v if selected, line level .
Common with pa speakers and would need a transformer to couple with the speaker . This will enable no voltage loss and little noise pick up .
Also you could series up separate speakers in the system each one having a transformer on the speaker connected👍
10V would be12.5W into 8 ohm speakers. Might be a little loud, but do-able.
@@russellhltn1396 yes but what they use to do was separate the output transformer from the power amp and run cables to it so that the resistance of the cable was no longer an issue that allows you to reduce the resistance of the cable running the speaker because you are running a higher voltage.
Then the speaker has the output transformer as well as the speaker . If you look on eBay eagle international made these transformers back in the day.
Just makes the output stage efficient to run long cables to speakers
The repair was impressive! Well done!

I suspect that the voltage setting is for an directly powered speaker and the resultant audio signal will be centered at 10V instead of 0V. You would need an inline capacitor or some other DC bias removal circuit to remove that DC offset, and that should make the audio louder and clearer. Worth a try :) Great video.
en.wikipedia.org/wiki/Constant-voltage_speaker_system - it needs a transformer :D
@@rcajavus8141 agree! I used to install these on jukeboxes in the 70s.
The voltage level is a nominal level of the audio output, not a DC bias. Higher voltages run lower current and can support longer runs of wire - which is important in malls or other large areas where nobody wants to pay for leagues of thick cabling. A transformer on each end converts the low-voltage AC to high voltage, then back to low voltage at the speaker.
