I'm blown away by how nice this set looks after all these years! It would have been pretty exciting for the original buyer of this to bring the bright red thing home to set up in the lounge.
I remember this chassis well, it was the lead to the degausing coil that must be kept plugged in. The one chip decoder was from the early batch of sets, the later 2 chip one is interchangeable. Like all designs of that era, heat was the cause of most faults, and the charred spare panels shows how bad they got, some were often beyond repair as the burnt areas became conductive. I was only 15 in 1970, by 1972 i was learning how to repair them along with all the other popular chassis from that time. That orange painted cabinet shouts the 70's some were in white which turned cream due to the heat. Happier days, when you knew the faults before you took the back of the set. Thanks for this trip down memory lane.🙂👍
I cut my teeth on the A823 chassis. What you have there is an early Murphy Acoustic with the one chip decoder, also the later models didn't have the two big pots on the timebase board. For the age of it looks very good. I've not seen one for over thirty years !
Watching this video brought back memories. We lived on an RAF camp in 1979. I was 16 at the time and always visiting the camp dump. It was fascinating to rummage through the items. One visit I came across this same model of TV in gloss white. It was soon on my trolley and being towed home. Turned out to be an easy fix as the HT lead was arcing to the chassis. It makes me smile now as I remember being so proud that I had this great looking TV for free. When we moved it went into my parents loft and most likely is still there as it weighs a ton. Not something you want to bring down the loft ladder!
Back in 1999, I repaired one of these, gave it a long soak test, and sold it to someone I worked with who lived up a long flight of stairs. Next day it broke down. He was very, very stroppy and threatened to wrap the TV around me. It went to the tip and I never worked on an A823 again. He also tried to chat up my girlfriend (now wife). When he was made redundant, I for one was happy to see him go. Funny the things you remember.
I could have told a story about 6 or 8 of these sets and two long flights of stairs but didn't want to make the video too long that people lost interest, I will maybe in another video ! In 1999 these sets were very old and not surprisingly un reliable.
I used to like these. I sold hundreds of Co-op ex-rental models of these. The faults were fairly predictable and the weak spots easily dealt with before sale. The LOPTs never, ever failed (well not for me anyway, I kept one spare LOPT in stock and never needed to use it). The mechanical tuners had a problem with the nylon nuts disintegrating which was a nightmare until replacements became available from the spares suppliers. (These days you could probably 3D print them!)
The first colour TV we had when I was a kid was a Rank Bush Murphy, it was around 1970, it had four very clunky pushbuttons to select the channels. It was built around plug in panels, I was fascinated when it went wrong my uncle used to arrive with a spare chassis of panels on a frame to get it going.
I too was fascinated when the rental man use to fix our Thorn 1500 set , he wasn't too pleased one day though when he came out because I had pushed all four buttons down together !
Another excellent video, thank you for sharing. I would like to know more about the process you describe as "reforming capacitors". Please could you do a video on the topic?
Of course but what most people don't realise this set new would have cost about the same price as a new LED set today , so taking into account inflation a new LED set should cost about £2,000 not 200 and this is why everything made now is just crap .
Fantastic Michael. I wish I'd kept one of these. I worked on many of them and, in later days, thrown many away. The early single chip decoders started off life with an IC with a built-in heatsink like the Plessey/Sinclair audio ICs of the day.
When I look back at the stuff I skipped many years ago I too wish I had kept hold of it , but then I didn't think 40 odd years later it would be making a comeback .
Good morning Michael. Today's video to me right back to 1973. This was our first television my wife and I bought after moving into our first home. Back then the TV engineer came into our home and set it up to make shure all was OK. Thanks for the trip down memory lane. Nice one.
nice, i repaired a bush ctv194 some years back, looks similar or same chassis, only fault was cracked surge thermistor, unfortunately it eventually got dumped, with an early version 26inch philips g8 when the garage owned by the sets owner closed down and was demolished for housing, if i had space i would have had them, but i was already bunged up, he'd given me loads of stuff like old unwanted tvs, valve radios, etc. over the years as he used to do tv and radio repairs many years back as well as run a garage,
customers used to like them with the matching stand. it was the lead to the convergence coils that must be pluged in to stop the resistor catching fire. In my opinion the single chip decoder gave a better picture than the twin chip and as far as i remember they were interchangable great video as allways.
The owner has the matching swivel stand but removed the stand before transporting it to me , I still cant remember what not to unplug , I just remembered it was easy to forget and cause a burn up .
That set is in excellent condition. I think you will have to look at the video coupling as I can see l.f. streaking. If this is sorted the picture will be as new. The single chip decoder board is correct for that model as it also has the earlier timebase board and mechanical tuner so all original. Loved working on these sets in the 70's, never had a line output transformer fail on one of these!
The picture looks better that it is in the video , good to know about the transformer, parts like this will not be obtainable now and I don't even know if anyone still does transformer re winding .
Isn't it just , love the colour , back in the 80s I was never a big fan of delta tubes , took too long to converge when your busy and then noisy wire wound pots would go intermittent when disturbed .
wow nice to see a good old Rank murphy colour tv up and running again they were so easy to repair and set up i had a white Murphy A823 with the six electronic tuners on the top of the set with the afc button on the top too and the colour decoder on mine had the Twin chips fitted
I cant remember the electronic tuned set so not sure why you would want 6 channel tuning in 1970 , we only had 3 channels up until about 1984 and I guess by then most of these sets would have been scrapped.
@@michaeldranfield7140 I agree there but they did have them on the Murphy ones and some of the Bush ones too but they were often flimsy and broke easily and some of the CRTS Would often display milky pictures if they were weak tubes plus had a fair few that had suffered catastropic power supply failures with the thyristor ending up destroyed and other problems like Video output transistors in the colour decoder failing but overall they were otherwise reliable Tv's
What a stunner!! Condition as well as the red finish and the resulting picture... just wonderful. We had one of these from around 1972-1980 in white; re-badged with the name of the rental company and I was only little but I've had my eyes open for any sightings of them ever since. 😀 I believe they were marketed as 'Acoustic Deluxe', along with the earlier mono sets with a very similar cabinet design. And they were available in green and orange as well - both mono & colour ones. Great to see - thank you.
Yes I do have recollections of the mono sets having coloured cabinets , cant remember the chassis number , I think it was something like 774 , I remember they had two boards .
@@michaeldranfield7140 hi and thanks for the reply. I've seen a very good thread on the radios-tv. forum in which a post lists variations of the monos which started life with the dual standard A640 chassis. Then the single standard is the A774 chassis; there was also a solid-state single A816. My parents also had one of these for a short time... I remember my mum telling me this... undoubtedly one of the latter two but wanted colour and the shop were not happy with them because they'd only just started renting the b/w one! I found the user manual many moons ago and so asked about it - why they had the wrong one, for a different set. But they didn't! 😆 As noted below, the actual colour set we rented would have been the later version - the tube surround looks a little different to this beauty on the video, as well as the channel selectors were very light to the touch, instead of the 'thunk' that my Ferguson Courier b/w has, along with countless others from the era lol. There are some nice advertising brochures for these sets online - I'd love to have them in my collection... I grab what I can from eBay when the price is right and do have a RBM tv colour catalogue from circa 1974, alas not having one of these on the pages.
I worked the solder bath at the end of the production line for the decoder panel at RBM in Plymouth 1974 ish and I remember there being 2 ICs on the board so the spare one may well be the later version. Part of the job was to make sure certain components were pushed down before soldering including those ICs, the pots on the RGB output and the delay lines. Thanks for the video, takes me back.
Fabulous stuff. A white one sleeps in my cellar. It's pretty rough, I think it also has the two chip decoder. I've also got the black and white version with the A819 (I think) chassis. One day I'll get around to it. Maybe......
@@michaeldranfield7140 They looked very similar to the 823 colour sets, a lot shallower of course. The Murphy ones were branded 'acoustic deluxe'. I've still got the pedestal stand, and they fetch good brass on ebay but I wanted to keep mine, I saved it from the bin when it came off rental in 1990......
@@stuartarundale6219 The customer has the matching stand for this set but removed it for transport, that's something you never see any more , stands for old TV s .
@@michaeldranfield7140 Indeed so. The stand for mine is unfortunately in rather the same condition of the set. It would have to be re-chromed if the set were ever to be refinished and restored. I can't even remember what condition the tube was in. Sleeping next to it is another uncommon white set, a Korting Transmare hybrid, in similar disheveled condition alas
Wow! Amazingly good condition for it's age. Looks like it was used quite a bit for a year or two and then never used again. Thanks for sharing! I cannot recall working on one of these myself. However, I do seem to recall one of the field engineers bringing one or two of these into the workshop to repair as a private job....
Great video Michael, that looks a lovely set. I haven't worked on one of those for many years but at one time did a lot of them, a friend of mine had around 200 out on rental.
@@michaeldranfield7140 : Totally agree with you, it really makes it stand out. I've never actually seen one that colour before. Around here you could have any colour you wanted as long as it was Brown 🙂.
Wow last time I saw one of those the insides looked like the spare panels you have ! That set must have been a leap year set and then only used a day per year lol
I would imagine a lot of these sets were scrapped due to pcb burnups , although it was in such good condition inside it did take a little longer for the red gun to come up to full emission .
Very nice set, loved that painted cabinet, they were ultra stylish back then, very well made and thought out chassis apart from the decoder which was a pig to work on due to lack of space, if you were an accredited rbm dealership a test chassis was available with a good set of boards extension leads and a 'second' crt, it wasn't particularly cheap but if you'd got dozens of them out on rental it was a good way of always having enough spare panels to support them.
Working at Rediffusion in the mid 70s it was mostly their MK1 hybrid but theY also had the A823s and BRC 3000/3500s. They even had some of the A823 chassis refitted into new cabinets with electronic tuners. I still remember changing those mechanical tuner plastic bushes from white to blue when they used to break and that carbon rod focus in the tower which scared me to near death.
when I removed the screening can my first thought was how to adjust the focus control, do you need a plastic tool , then I noticed its on a screw arrangement down a hole .
This looks so different from an American TV. The overlay on the convergence controls looks very useful I have never seen that before on our TVs. In 1970 we didn’t have many solid state color TVs.
I had an identical set back in the late 70's, the colour was called "Outrageous Orange". These are a really sought after set these days, also known as the "Acoustic deluxe".
Oh, nice one mate, been looking forward to more colour tv videos! i remember MURPHY well, until the chinese got hold of the brand name and started churing out plastic rubbish, love the colour of this television, its epic. this is literally a COLOUR tv
7:20 - the single chip decoder indicates that’s a later board so the picture will tint slightly towards green. February 1970 date code on the caps indicates an earlier A823 though, so that decoder board has been swapped at some point. Unless RBM were just using up older stock of new caps when this was made?
as it came with a couple of spare boards which had both been worked on I would think this came from an EX collector or enthusiast. I still have not found the service manual , I have it somewhere , I remember it had a brown front cover ., so not sure of the exact dates or decoder arrangement .
Very unusual to see in such a clean form. Those two extra PCBs seem to be its past repair history. Wish I could remember nowadays to reform the reserviour cap before switch on. So many times on an instrument amp especially I've had to replace one because I forgot completely. Maybe having a purpose made reforming box like you use would remind me.
Other people have commented that the single chip board was the correct one for the year of the TV , so I would imagine the other boards have been used for fault finding , a thing I hadn't noticed in a plastic bag there were a set of decoder extension leads so I would guess at one time this set would have been owned by a collector .
So did you pick the jumper to match the set? lol Another good video Michael I like to watch how others go about fault finding with or without the service manual
I have always loved bright colours and this is more than likely why I got into electronics in the first place , brightly coloured components . I have the full service manual somewhere ,just couldn't find it at the time .
Vertical still has a bit of residual bent at top but not noticeable. Though having said that, when I saw the kink before the dried out EB cap changed it seemed to me it was very slowly moving upwards out of frame and into blanking.
I briefly worked in Quality Control at Rank Bush Murphy in Plymouth whilst this set was in production. The strangest version I saw was made for Ringo Starr with a stainless steel veneer on the cabinet; I didn't like the look personally, I preferred it in white.
That's a early A823 with mechanical tuner unit fitted , the later ones had a 6 button switch bank .I think the decoder used to have 2 chips fitted SL901 /SL917 ? comes to mind . Not bad picture for a 50 year old tv not had much use by the looks of it .Murphy did them in Red , White, Green ,Blue as far as I remember with optional swivel stand .
I do remember the red and white very well but not the other colours, the owner also has the matching swivel stand , he removed the stand for transportation to me .
@@michaeldranfield7140 I do remember seeing mono sets one with a green cabinet with dual standard a640 chassis and several white cabinets fitted with the single standard a774 chassis
So nice to see where some of these effectively defunct brand names came from. Bush and Murphy names just tend to represent cheap and mostly poorly made junk these days. I used to buy and repair a lot of ex-catalogue returns in the 90's. Murphy stuff in particular was always really cheap and nasty, as was Alba, Bush etc.
sadly now the Bush and I think Alba brand names are just owned by Argos and as you quite rightly say these once great British companies are nothing more than just a name for junk now .
Thank God for EU energy labels. Lots of resistors that are basically just heating the inside of the cabinet. Some older sets would, when they're turned off, still keep the tube filament heated, so you wouldn't have to wait for it.
We had a set that looked similar, but it was black and white and a wood veneer cabinet. I remember it failed under guarantee and my parents sent it back to Comet for repair. They had it for about 2 weeks before diagnosing line output transistor failure. Mum was not impressed with the repair department!!
IC's and 2 chip decoder? ... In 1970, I was watching a 1960's Ecko black & white valve powered 405 line Rediffusion TV with a clicky channel selector on the wall! 👎🤣 ... My father bought his first Ultra Bermuda Colour 26" TV from Trident in 1973 for £300 IIRC. It was solid state, but contained no IC's!
I remember the a823 thay where very reliable sets linear psu the worst thing was the colour decoder those CMOS chips one flash over an thay where agoner. Ha
I have a circa 1980 SONY 26"" Multi-System TV sitting in the Garage for decades - It was built by SONY in Germany and cost a fortune New. At almost $2300 as near as I recall and double the price of a commonly available domestic TV. It failed after only 3 months of use - as it was under warranty - back to SONY it went --- They could not repair it and ordered a replacement from Germany that took 6 weeks to arrive and another two weeks for SONY to replace it and/or complete the repair - ready for collection. Just prior to the warranty expiry period - it failed again. I said - Screw it - and instead - I repaired it myself. *Having studied Electronics Engineering with PHILIPS I can only say that it was a pain in the neck to work on - complex circuitry --- nevertheless it operates on various AC mains voltages /f and all the variations of PAL - NTSC - SECAM and Middle East SECAM It would have been great if the TV even existed in 1974 when I was on attachment to the USAF for two years There is also a 26"" GRUNDIG in the Garage with a faulty [Thyristor] Horizontal Output Stage - The CRT is excellent on both TVs It will make an interesting project to restore them. The downside is that the GRUNDIG as well as other German sets such as NORDMENDE - SABA -GRAETZ were not well suited to the warmer climate in Australia - unless one happened to be in the mountain and southern colder / and snowy regions. The German sets operated at an elevated temperature - destroying components and Circuit boards - and were very power-hungry - and they were very good room heaters during winter evenings, Besides those - I have two SONY 21'' Computer monitors - one of which is rebadged as IBM - they cost me $5000 each NEW -- years later I found one that had been dumped by Sydney Based Modelling agency - HQ in Paris France -- I discovered that it had a broken pin on the CRT -- fortunately the CRT is still under Vacuum.
CRT The quality of picture is superior to modern LED screens Modern TVs have what I call a mushy picture quality and lack of natural colour I suppose one has to have a convertor to run a CRT TV from digital ?
You just need an old sky box with RF out to run and old CRT set, I agree some of the pictures on CRT , especially some Sony sets were far better than LCD .
The original caps built with will often outlast modern replacements if they're reformed. Forming and reforming was actually important task back in the days of valves (tubes stateside). Nowdays wet aluminium are pre-formed at the factory, put into use before losing form and become the popular subject of 'change all the caps'
I'm blown away by how nice this set looks after all these years! It would have been pretty exciting for the original buyer of this to bring the bright red thing home to set up in the lounge.
I think Bush did some black and white sets if painted cabinets too , the owner also has the orig swivel stand with this set.
Had friend way back 1970 his parents had a Nordic TV set on a steel pedestal .

There are some nice advertising brochures for these sets online - I'd love to have them in my collection... I grab what I can from eBay when the price is right and do have a RBM tv colour catalogue from circa 1974, alas not having one of these on the pages.
@@IanAKAKeith I have just joined the radios TV group, this guy has a stunning collection of sets , far better than mine .
I worked the solder bath at the end of the production line for the decoder panel at RBM in Plymouth 1974 ish and I remember there being 2 ICs on the board so the spare one may well be the later version. Part of the job was to make sure certain components were pushed down before soldering including those ICs, the pots on the RGB output and the delay lines. Thanks for the video, takes me back.
No problem , glad it was of interest and helps to bring back valuable memories for you .
Fabulous stuff. A white one sleeps in my cellar. It's pretty rough, I think it also has the two chip decoder. I've also got the black and white version with the A819 (I think) chassis. One day I'll get around to it. Maybe......
I remember there were black and white sets in bright gloss cabinets , line transformers were a common failing on the mono sets.
@@michaeldranfield7140 They looked very similar to the 823 colour sets, a lot shallower of course. The Murphy ones were branded 'acoustic deluxe'. I've still got the pedestal stand, and they fetch good brass on ebay but I wanted to keep mine, I saved it from the bin when it came off rental in 1990......
@@stuartarundale6219 The customer has the matching stand for this set but removed it for transport, that's something you never see any more , stands for old TV s .
@@michaeldranfield7140 Indeed so. The stand for mine is unfortunately in rather the same condition of the set. It would have to be re-chromed if the set were ever to be refinished and restored. I can't even remember what condition the tube was in. Sleeping next to it is another uncommon white set, a Korting Transmare hybrid, in similar disheveled condition alas
Wow! Amazingly good condition for it's age. Looks like it was used quite a bit for a year or two and then never used again. Thanks for sharing! I cannot recall working on one of these myself. However, I do seem to recall one of the field engineers bringing one or two of these into the workshop to repair as a private job....
Its hard to believe how old this set it and just look at the engineering that want into making it, its a far cry from the crap we make today .
@@michaeldranfield7140 Yes indeed, this old one was built to last...
spent many hours working on these , and that one is a corker . lovely to see these old sets again michael
Unfortunately this one is not part of my collection .
Great video Michael, that looks a lovely set. I haven't worked on one of those for many years but at one time did a lot of them, a friend of mine had around 200 out on rental.
I love the cabinet colour .
@@michaeldranfield7140 : Totally agree with you, it really makes it stand out. I've never actually seen one that colour before. Around here you could have any colour you wanted as long as it was Brown 🙂.
@@rscelectrical7091 I remember , first it was brown , then black , then silver was the trend , how dreadful was a silver tv in the 90 s .
Wow last time I saw one of those the insides looked like the spare panels you have !
That set must have been a leap year set and then only used a day per year lol
I would imagine a lot of these sets were scrapped due to pcb burnups , although it was in such good condition inside it did take a little longer for the red gun to come up to full emission .
Can't believe the set is 50 years old... you can't beat CRT for picture quality. Great video.
too right , CRT it tried and tested technology .
Very nice set, loved that painted cabinet, they were ultra stylish back then, very well made and thought out chassis apart from the decoder which was a pig to work on due to lack of space, if you were an accredited rbm dealership a test chassis was available with a good set of boards extension leads and a 'second' crt, it wasn't particularly cheap but if you'd got dozens of them out on rental it was a good way of always having enough spare panels to support them.
I guess if you had a scrap set for the plugs and sockets you could make up your own set of extension leads .
Nice retro set mate i bet it's a long time since you found one as clean as that inside
Love the orange case , very retro .
Great vid as usual, thanks.
Many thanks for that , more coming soon .
Wow a Beauty
It is and the colour of the cabinet is the best , I like bright colours .
Working at Rediffusion in the mid 70s it was mostly their MK1 hybrid but theY also had the A823s and BRC 3000/3500s. They even had some of the A823 chassis refitted into new cabinets with electronic tuners. I still remember changing those mechanical tuner plastic bushes from white to blue when they used to break and that carbon rod focus in the tower which scared me to near death.
when I removed the screening can my first thought was how to adjust the focus control, do you need a plastic tool , then I noticed its on a screw arrangement down a hole .
This looks so different from an American TV. The overlay on the convergence controls looks very useful I have never seen that before on our TVs. In 1970 we didn’t have many solid state color TVs.
This comes from an age where we atcually made stuff in the UK , and where manifactures backed up there products, sadley all gone now .
I had an identical set back in the late 70's, the colour was called "Outrageous Orange".
These are a really sought after set these days, also known as the "Acoustic deluxe".
I can see how this colour would be the most sought after , I love it .
Oh, nice one mate, been looking forward to more colour tv videos! i remember MURPHY well, until the chinese got hold of the brand name and started churing out plastic rubbish, love the colour of this television, its epic. this is literally a COLOUR tv
yet another famous manufacture gone down the pan , I think some 14 inch fidelity sets were badged murphy in the 80 s .
Remeber these well when I worked for
Wetherheads TV
I have very limited memory of these sets, its a long time ago now .
Our first color tv, remember them well , crt is excellent for a 50 year old set ,unbelievable really.
7:20 - the single chip decoder indicates that’s a later board so the picture will tint slightly towards green. February 1970 date code on the caps indicates an earlier A823 though, so that decoder board has been swapped at some point.
Unless RBM were just using up older stock of new caps when this was made?
as it came with a couple of spare boards which had both been worked on I would think this came from an EX collector or enthusiast. I still have not found the service manual , I have it somewhere , I remember it had a brown front cover ., so not sure of the exact dates or decoder arrangement .
Very unusual to see in such a clean form. Those two extra PCBs seem to be its past repair history.
Wish I could remember nowadays to reform the reserviour cap before switch on. So many times on an instrument amp especially I've had to replace one because I forgot completely. Maybe having a purpose made reforming box like you use would remind me.
Other people have commented that the single chip board was the correct one for the year of the TV , so I would imagine the other boards have been used for fault finding , a thing I hadn't noticed in a plastic bag there were a set of decoder extension leads so I would guess at one time this set would have been owned by a collector .
I'm surprised. 1970 and fully solid state. With a big integrated Circuit to boot. Looks great!
i had the white version of this with the Murphy badge and the cross feet stand .
I remember the white one , not sure but I have a feeling they may have been a green one as well.
yes there was a green one and a blue one@@michaeldranfield7140
So did you pick the jumper to match the set? lol Another good video Michael I like to watch how others go about fault finding with or without the service manual
I have always loved bright colours and this is more than likely why I got into electronics in the first place , brightly coloured components . I have the full service manual somewhere ,just couldn't find it at the time .
Vertical still has a bit of residual bent at top but not noticeable. Though having said that, when I saw the kink before the dried out EB cap changed it seemed to me it was very slowly moving upwards out of frame and into blanking.
I didn't see it moving and digital cameras never seem to take good pictures of television sets
I briefly worked in Quality Control at Rank Bush Murphy in Plymouth whilst this set was in production. The strangest version I saw was made for Ringo Starr with a stainless steel veneer on the cabinet; I didn't like the look personally, I preferred it in white.
When you look at modern sets its hard to believe how poor quality they are compared to the solid construction of this set .
Lovely example, if that needs to find a home I would be interested!
Its not actually part of my personal collection, one of my viewers set it in for re commissioning, it will be going back next week .
@@michaeldranfield7140
Ah, shame. Well, if ever the owner wants to move it on, he has a buyer here👍😉
That's a early A823 with mechanical tuner unit fitted , the later ones had a 6 button switch bank .I think the decoder used to have 2 chips fitted SL901 /SL917 ? comes to mind . Not bad picture for a 50 year old tv not had much use by the looks of it .Murphy did them in Red , White, Green ,Blue as far as I remember with optional swivel stand .
I do remember the red and white very well but not the other colours, the owner also has the matching swivel stand , he removed the stand for transportation to me .
@@michaeldranfield7140 I do remember seeing mono sets one with a green cabinet with dual standard a640 chassis and several white cabinets fitted with the single standard a774 chassis
If I remember it had valves in them last one I had was in 1997 and the problem I had with it had the back off the tube in half
There was a black and white version of this set in the orange cabinet that was a valve TV .
So nice to see where some of these effectively defunct brand names came from. Bush and Murphy names just tend to represent cheap and mostly poorly made junk these days. I used to buy and repair a lot of ex-catalogue returns in the 90's. Murphy stuff in particular was always really cheap and nasty, as was Alba, Bush etc.
sadly now the Bush and I think Alba brand names are just owned by Argos and as you quite rightly say these once great British companies are nothing more than just a name for junk now .
The deguass plug if left unplugged will cook the 680 ohm resistor
I thought it was something to do with degaussing .
Hi Mike I've one of them sets but red raster and flyback lines on the screen. What would cause that. 26 in mullard tube
Apart from the few wee marks you'd think that set was pulled straight out of the box 😮
My apprenticeship tv…crunchy convergence pots… thyristor power supply…poor 20’’ Toshiba tubes …
Its surprising just how hot these wire wound pots run .
Wasn’t it a BT106 thyristor bolted to a heat sink and hardwired to the board?
@@steve83803Yes BT106 , a few set makes in the day adopted the same thyristor power supply.
That one is a823a I think one CMOS chip in the decoder
I never ever remember seeing one with a lopt failure
Thank God for EU energy labels. Lots of resistors that are basically just heating the inside of the cabinet.
Some older sets would, when they're turned off, still keep the tube filament heated, so you wouldn't have to wait for it.
We had a set that looked similar, but it was black and white and a wood veneer cabinet. I remember it failed under guarantee and my parents sent it back to Comet for repair. They had it for about 2 weeks before diagnosing line output transistor failure. Mum was not impressed with the repair department!!
IC's and 2 chip decoder? ... In 1970, I was watching a 1960's Ecko black & white valve powered 405 line Rediffusion TV with a clicky channel selector on the wall! 👎🤣 ... My father bought his first Ultra Bermuda Colour 26" TV from Trident in 1973 for £300 IIRC. It was solid state, but contained no IC's!
I remember the a823 thay where very reliable sets linear psu the worst thing was the colour decoder those CMOS chips one flash over an thay where agoner. Ha
I have a circa 1980 SONY 26"" Multi-System TV sitting in the Garage
for decades - It was built by SONY in Germany and cost a fortune New.
At almost $2300 as near as I recall and double the price of a commonly
available domestic TV.
It failed after only 3 months of use - as it was under warranty - back to
SONY it went --- They could not repair it and ordered a replacement
from Germany that took 6 weeks to arrive and another two weeks for SONY
to replace it and/or complete the repair - ready for collection.
Just prior to the warranty expiry period - it failed again.
I said - Screw it - and instead - I repaired it myself.
*Having studied Electronics Engineering with PHILIPS
I can only say that it was a pain in the neck to work on - complex
circuitry --- nevertheless it operates on various AC mains voltages /f
and all the variations of PAL - NTSC - SECAM and Middle East SECAM
It would have been great if the TV even existed in 1974 when I was on
attachment to the USAF for two years
There is also a 26"" GRUNDIG in the Garage with a faulty [Thyristor]
Horizontal Output Stage - The CRT is excellent on both TVs
It will make an interesting project to restore them.
The downside is that the GRUNDIG as well as other German sets
such as NORDMENDE - SABA -GRAETZ were not well suited to the
warmer climate in Australia - unless one happened to be in the
mountain and southern colder / and snowy regions.
The German sets operated at an elevated temperature - destroying
components and Circuit boards - and were very power-hungry -
and they were very good room heaters during winter evenings,
Besides those - I have two SONY 21'' Computer monitors - one of which
is rebadged as IBM - they cost me $5000 each NEW --
years later I found one that had been dumped by Sydney Based Modelling
agency - HQ in Paris France -- I discovered that it had a broken pin on the
CRT -- fortunately the CRT is still under Vacuum.
CRT The quality of picture is superior to modern LED screens
Modern TVs have what I call a mushy picture quality and lack of natural colour
I suppose one has to have a convertor to run a CRT TV from digital ?
You just need an old sky box with RF out to run and old CRT set, I agree some of the pictures on CRT , especially some Sony sets were far better than LCD .
I saw worse condition sets in the 70s - wow!
Took a little while for the red gun to come up but overall yes its a good set this .
How to help😮
Reforming is not worth it !!
The original caps built with will often outlast modern replacements if they're reformed. Forming and reforming was actually important task back in the days of valves (tubes stateside). Nowdays wet aluminium are pre-formed at the factory, put into use before losing form and become the popular subject of 'change all the caps'
@@jagmarc - That was back then.
