The Guitologist Can any triode tube be used as an amplifier?
The Guitologist hmm didn’t know yellow tape was established in 1833 lol
Love your custom morton shirt :p
That amp whinced when you took those wire cutters to it! Felt it all the way to here in the UK! Your so right about Brussels, thats why we are coming out of the EU. Lovely piece of US electronic history. Love it !
In 1983, the bigger the better. We would haul cabinets that didn't even work just to make our sound look bigger. Today, I'd rather take a little tube amp like this Magnatone and a mic. So it is in life. Big amps and big hair to small amps and no hair...LOL.
Good job all around. I enjoy repairing these old small amps, keeping them being played through. Mark
I have to fight myself from scrolling forward to hear you make her sing. And congratulations on striking a sponsorship deal!
That amp sounds just beautiful. Your playing at the end sent me into daydream land reminiscing about my growing up with music. Thanks for the killer videos.
Man...I love this kind of video: old gear in average condition, few parts to be replaced and, when complete, a great sound coming from its guts. Greetings from Brazil.
Me too, Leonardo. Love when a plan comes together!
I really enjoy your channel Brad, that is when I have time to watch it. We're in the same biz but It's hard for me to keep up with my customers and I don't even advertise much less video my repairs. Oh well keep up the great work Dude!
Excellent episode thanks Brad! Damn, that little thing sounds awesome!
Love the channel , and im always learning new things..love old vintage amps . the insides warm my heart ..cheers
The only thing better than seeing and hearing them is SMELLING them while they're cooking. Love that smell. I should create my own cologne and sell that instead of t-shirts.
Most of the time I'm sitting there in silence, just watching you working, but then you put in those little video sequences and I burst into laugh because they are so on spot funny and unexpected!
I "grew up" as a young engineer for IBM. They were sticklers for equipment grounding, and had a strict rule against using 'functional screws' for grounds. While I understand their thinking there is NO way I would drill a hole in that nice old amp either! If you clean the chassis and use an existing screw you will never have a problem. I would use a star washer. That was another thing I learned at Big Blue.
I agree. I would normally not consider grounding to a component bolt, but in the case of this amp I would make an exception. I would fit a locknut in addition to the star washer.
what is the theory behind not using a "functional bolt/screw" as ground...? ...because it may potentially work loose?
Would be so nice to have a amp like that. Sounding good, and looks good, specially after you put your "love" into it. Great job, once again Brad. Nice playing by the way, we sometimes forget that you are a good guitarist.
Love your videos brotha.
Usually it's easy for guitar repairs for me but amps always been more complicated for me.
I've learned to much since I've been watching your videos. 🤘🏿😈
this diminutive old amp has some awesome break-up tone
after 70 some years ,has R&D improved what is still so
appealing from small valve amps, ? great work brad,
Totally agree with hot glue speaker repair method , I seen it on one of older videos and used it , works perfect as long as one is careful and uses a thin layer
The intro is too funny! Love your sense of humor Brad!
nicey amp!!!! super that uncle doug is back in youtube land- in my younger age im working as car electrics+mechanics-specialy old/youngtimers+ soundsystems. i had a vw-kaefer 1200
6 volts-ichanged the komplete electric to 12volts. this was in 1979 -i was 17/18 jears young
hey brad-the last 2 days in vienna the winter comes back-snow and minus 7 degree-
the best time to heat on a tube amp ! i started to get naked outside- in the middle of the street-
to cry +scream long live the guitologist! -but too cold for this! rockn rolly brad!
Amazing how these little vintage practice/student amps can be crunch monsters.
Those hairlarious video inserts! I’m on the floor! Another informative and amusing video! Thanks mr Guitologist
That amp rocks!!
With regards to the "local cap sourcing", beginning in 1948, there was a post-war 'consumer electronics boom', dealers couldn't keep tabletop radios (which occupied most kitchen tables) in stock, because of "tensions" resulting from the inception of the Cold War. By late 1950, housewives were advised to "keep an ear on the radio throughout the day", because of the recent USSR entry into the atomic era. Television manufacturers were also running "in full-blast" production mode. The consumer electronics boom accompanied the housing boom, and the "Baby Boom". Parts shortages were prevalent, as most component manufacturers were contractually obligated to the "big electronics manufacturers"; it was "source from wherever you can find it, or shut down production".
The parts shortage situation began to resolve in early 1952.
You're right about the post war boom in the US. We weren't hit with the austerity seen in Europe and the rest of the world touched by the War. Our factories were still standing over here, and they wen't wild immediately. You see more vintage radios dated 1946 than any other single year.
Also got to keep in mind that the Chicago area was a major electronics production hub in the U.S. until it all up and went overseas and was gone by the end of the 1980s. Zenith, Motorola, various brands sold by Sears, and who knows what else. Only makes sense that most of the components for making all those TVs, radios, and stereo stuff was made in the area too. And it didn't hurt that that the city was (and still is) a major shipping and transportation hub.
Yes, but you're also talking about a time before the interstate highway system and commercial aviation really took off. So shipping from Chicago to LA was a chore.
Route 66. Also, capacitors weighed a lot less than transformers, so sourcing the heaviest parts locally would have been more important.
The "Chicago School of Electronics", the best, anywhere, and at anytime in history. Motorola - nicest construction; Zenith - best designs, excellent quality; Admiral - honorable mention; E.H. Scott (during his working life) "all of the above, produced the best radios of all time".
To see it now saddens me.
Man that little amp sounds good! I’ve always been a BF Fender clean/Vox chime/tweed fender blues/Marshall crunch type of guy and would personally take these sears catalog type amps and mod them to fit one of those profiles....but I believe you did the best thing possible for this amp! I need to find me one now to restore!
Love the tape over the Logos! Nobody Rides For Free! Haha! That amp sounds killer for a 1949 student model, just goes to show the superior tone of even the simplest of tube circuits! Great speaker repair tip too! Thanks Brad!
Yep, fuck 'em. Let 'em walk.
Great Job indeed. I am basically a novice, yet have repaired a number of vintage amps for my own personal pleasure . Far as using the transformer bolt for a ground ,is what I have always done , with zero problems :)
I couldnt imagine that any guitar enthusiast would be a bad player, but I gotta say.. you always seem to play suit to the gear you repair very well! You`ve got some great tone in your hands let alone the pensil you use to write it through. Bravo man, great content/content coverage!!
Wow, thanks Rory!
Love watching people who know what there doing! 🤘
Hey man! I just don't know how I endup here, but your videos are too satisfying! Good job!
Love this... What a cool little amp. I bet that guy is happy happy happy. Thanks for sharing.
I'm liking the new editing.
Great Vid, nice fix! Sounds Awesome. Thanks for sharing.
Noodle King! Another back from the dead. I had an early 60s Ampeg amp that sounded exactly like this one. Same tube complement and speaker. Great video, by the way! Thanxz
Sounds great, good work!
Great repair job, customer will love this amp now.
I think so.
I love this shit. Great video. A+ on the editing efforts, too.
Hi l have watched heaps of your your shows and l have learnt a lot
I just wanted to say thankyou for your time
Without stating the obvious, they just don't make shit like that anymore. Love your vids...even though I haven't a clue what you're doing ! therapeutic !
What a beauty of an amp.
I'm with you on not drilling holes on vintage chassis. You can accomplish the same thing using existing hardware.
That was some improvement. Well done. Again.
I wish modern amps had this retro look! So cool and classy! Hey, where's the tape over the head stock! lol... !!! That amp tone is simply wonderful!
Thanks for the reminder! Mustn't lose revenue.
What a glorious little amp!!! Had an Esty Mag 1-10 (213?) that i loved. Nice to see something earlier so sweet.
Love how simple that thing is.
Thx for showing me the fuse ....out of storage it was somehow misplaced. Nice rebuild!
And so the student becomes the master:D But seriously what an amp that can be a "Secret Weapon" in a studio with tone for days. Amazing what those once flogged at "Beginners" end up being iconic in retrospective...
Love your videos. I repaired one of my speakers with black RTV
That's a neat little unit. I'd love to hear that with some Sprague and Mullard Mustard Caps. I used to go through the hassle of placing the caps inside the old can. Regardless I like the idea you left the can for looks purposes. Personally I would have been so tempted to hot rod that bad boy but, not wreck the chassis. Let's face it, there are tons of mods one can do and still keep the vintage factory looks. Shhhhh, it's our little secret. Keep it under your hat. LOL
Glorious! Tone for days!
Brad, you need some "Guitologist" shirts to wear in your videos. You could probably sell them, too.
I´m in for a shirt...already have plenty of EEVBlog, ElectroBBOM, AvE....
I'd buy them!!
I knocked the swag thing around in my head and I'm not really sure about it, but I have another idea I might go with.
A lot of TH-cam people use things like Tee Spring so they don't have to hold stock mail it out. Just submit the design and get the royalty payment. Kinda makes sense.
@@TheGuitologist If you decide to do a shirt, shoot me a message.
I will work you up a design in exchange for a shirt.
I've been in design for more than 40 years, so I ain't no rookie.
sounds great - what a great amp
A Weber Speaker would really open up this amp. They make a Champ replacement that is close to the output transformer and once broken it the champ becomes an amazing Amplifier. Thanks for the restoration.
Hot glue seems to work good! Years ago before hot glue guns, we used tissue paper and finger nail polish...it worked, lol. Btw...gorgeous guitar!
I just love the tape and having seen your Friday thing I get it!!
Nice sound and tone... Great service Job!
Worth it for the intro alone!
Sounds great!
Brad your the man.Love that remark on the Brussel's Bastards in the EU.We got more of em this side of the pond in Britain. Really enjoying your series really really interesting,riveting in fact. Phil. Wirral England.
lovely old amp well done restoring it
Have a lot of friends that worked at or retired from that Delco plant in Kokomo. Nice job Brad, good sounding practice amp.
I used to live down in Evansville. All kinds of stuff made up in Kokomo. Isn't Weber Speakers located in Kokomo?
Sure is. Kokomo was once a booming industrial town. Chrysler's main transmission plant, Continental Steel, Haynes International, Delco Electronics (GM) and Weber Speakers are just a few. Chrysler now has three plants in the area, but are not at full production as far as I know. I used to live pretty much dead center between Kokomo, Lafayette and Indy. I just recently moved to Ohio north of Dayton. I still go back and see my friends in the area a few times a year.
Man that PRS snarls.I think Im in love.
Uncle Doug would love that cabinet and covering. Great rebuild😁
Doug has impeccable taste.
sound's just like the fender champ clone's i make, nice and simple wiring and only a few component's, which is how i like it as i'm not that savvy with anything more complicated, lol,
nice work as alway's brad,
Thanks, Paul. You can really get a lot of juicy vintage tone out of one of these old SE Class-A type amps.
Great job 👍🏼
Great video as always!
Kudos Brad on the ground wire positioning.
Thanks, Carl. Sometimes the best policy involves a giant middle finger.
Because of the deteriorated rubber gasket around the speaker, there are probably graduals of it in between the voice coil and magnet. As it is non ferrous debris, a vacuum cleaner with very light suction should pull that out and then the slight coil rub sound will lessen or even be eradicated. Great to see an artist at work Sir, most informative Video, keep up the good work :-)
Best post in English this month, sir. Inter-synonym Overdrive. "Graduals" is excellent.
Great video like the eyes 👀 on the brush
Greets from Antwerp, Belgium Brad!
For 1949 technology, that little amp sounds killer. Rocking for its time for sure - we take for granted that, at least to my knowledge, the SLP wasn't even a thing in 49. Awesome job! Maybe you could do a tag on video to show how that one stage was grid-leak biased on schematic which is different from cathode bias?
Love the taped up Logos in the intro. "Make dem suckas pay!!!" Great video!
Chu! Dem Suckas ain't gon know what hit 'em.
dem suckas might not even know it was them! ;)
What a sweet little amp. I want one
It's funny cuz way back when when an amp distorted we thought it was broken times have changed. another great video. Haha I was thinking if you do a gear demo and it didn't sound good you could take it apart and make it better. LOL
Another gem , sounds great !! For cone tears , it depends on what the cone is made of. Un treated paper then tight bond 2. Treated paper the spacial cone glue. But nothing sounds better than an intact cone. Just ask the Cone-heads !
Sweet amp!... thanks for sharing :-)
Very unique tones....I like it.
Great work Brad I have been watching since last weekend, very interesting tips on how amp's work. Guitar players should be able to look out for this shit that we get from the guitar shops. I have a Hughes & Kettner 20th Anniversary 20 watt amp 2008 kicking arse with tubes.
Thanks for your reply and tips. Big salute from Anth in New South Wales, Australia.
Love you stuff my friend, have learned a lot thank you. I was wondering how come you never use a bulb limiter ever to test some of these amps?
Great all round video bro sure makes a good noise now. ATB
totally true, hotglue is the thing to go for when it comes to repair vintage speakers having a hard suspension...i done this so many times as well....:)
Great video, no free ads for tshirt or hat company, but maryland usa based prs gets a free plug. I like it
You made out like joran van der sloot in this one. Keep up the good work
In addition to being an awesome video I appreciate your little tips like the stripping wire trick at 12:38 :)
Sounds great, that little thing! :)
Thats a rockin little amp!!!!!
Totally agree with you on not drilling holes in Vintage kit, I'd always Earth to a good chassis bolt.
hard to be that old tube sound great job bud hi from canada
Just want to say learned a few great tips today. Paint brush for dusting, hot glue for speaker cone repair. I usually use contact cement and it’s a pain in the ass. Has a toxic smell to it and take forever to dry. Those old Chicago caps suck for some reason. I had a few dielectric Chicago caps either blow out their insides everywhere or start smoking inside the amp, either scenario is a mess. Makes you think Leo knew this and why he used molded caps instead. Thanks for the tips!
Any caps of this age will need to go, pretty much, even the molded ones. They are just way past their use-by date.
Hi, when removing the death cap, and adding a 3 prong grounding cord, how do you determine on the power transformer which is neutral and ground if they are both the same color? I’m assuming neutral was connected to death cap to chassis but not sure.
nice ! sounds warm
Brad, you seriously need the Hayco tool. It is worth every penny. Especially for installing the new one. Carry on. Robert
I dig the yellow tape across the CF Martin logo on your tee.
All those old leatherette,crocodile, alligator combos are BAD ASS, all day long.....
I had an old grill cloth that I re-purposed onto another amp. I actually did a gentle hand wash in woolite and it cleaned up nice and looked almost brand new.
You can take out old yellowed Fender grills and hose them down on the driveway and get a lot of that gak out of them.
HA I'VE done that before too. A guy gave me one he had still on a baffle board. It was from an early 70s Fender amp and I took the hose to it and it turned out nice.
That amp just sounds like Rolling Stones to me nice job!
You could start up a Stryper tribute band with that outfit!
do you think it makes sense replacing capacitors on a 1989 jcm800? what improvement should I possibly expect?
All of us tech could wright books on the crazy stuff we run in to.
Regarding the ground/earth connection of the power cord, modern product standards require that a fastener dedicated to securing ONLY the ground connection be used. This is to prevent the ground wire from accidentally being removed while servicing the equipment.
In this particular case, I understanding not wanting to drill a new hole in a vintage chassis, but if you're going to use an existing fastener, I would have picked one where it's easy to see whether or not the ground is secure.
I just love to hear you play...
I love that handle.
I know, right! It's beautiful. You NEVER see those still on the amp.
Brad the badass guitologist.
