Need help finding vintage guitar amp power transformer

[pdf64]

Everybody`s skils are too basic for that
...
Forget building the actual reverb tank itself, nobody does, not even mighty Fender/Marshall/Yamaha/Roland/whatever.
weīll suggest a modern Belton tank replacement (only remaining Factory in the World, that should tell you something).

I'm sure a certain J M Fahey could build a suitable (probably better) reverb tank if other sources dried up

CE and TAD advertise own brand tanks, I've read that the CE are Chinese https://www.tubesandmore.com/tech_co...d_and_compared

The TAD ones come from the same factory as the MOD ones (which sound great my the way) so I understand, .

My guess is an 8EB2C1B will work for you. It's 9.25in long.

I didn't realise you were trying to operate with the transistors not mounted to the heatsink. That was a really bad idea. They may now may be damaged and, assuming they are operating to some extent, only use them until you get the amp working and then replace them.

hey guys, got the amp working and its sounding great. I will order the two new transistors and replace them when they come in. my dumb self was trying to insulate the transistors with artic silver which I have used to repair some xbox 360's in the past, not realizing that it is conductive, HELLO!!! it has silver DUH McFLY!!!!

so I cleaned all the silver off and got 2 new micas and a ceramic non conductive compound from the shack, at very exorbitant prices one might add, and its all good.
I'm going to look into that reverb tank. If you guys think it will work. I have to admit this thing has some sexy grunge to it as it stands. I will post a youtube video when I have more confidence in my abilities as a guitarist.

thank you all for not slamming me for my inexperience and sometimes naïve questions.
rock on all.

In fact I DO build my own reverb tanks, but itīs a mess and I didnīt want to give the OP crazy ideas

But do you take apprentices? I'm only half-joking...

Like many things, they are not actually difficult to make, at all , you just need to get all parts and then assemble them: look at any reverb tank and you see all the parts,thereīs nothing hidden or NASA spec: delay springs, "guitar string" end loops and supports, pencil lead size hollow cylindrical magnets, coil bobbins, the winding itself, bobbin cores (I used small E laminations for transformers), L shaped brackets to hold the ends, ballpen tank sized brass tubes through which end "guitar strings" go through and which are packed with foam to provide damping, end eyelets through which string springs pass, plus a bent metal "tray" to keep everything in place.
Optional: external case, spings for floating, RCA jacks.

Of these, the real critical parts which stop home builders from making their own are:

* delay springs.
No big deal, any spring maker can make them if you supply a suitable sample.
Problems: minimum order will be 1000 springs , enough for 500 cheap reverbs or 250 good ones.

* tiny hollow magnets.
Thatīs the real bottleneck: not a standard part, I bet any Chinese or Korean maker (doubt any US based one remains) will ask for at least 50K or 100K initial production, plus you have to pay for the dies.

I am lucky to live in Argentina where we used to have a thriving independent Industry, (*we* used to sell Electronic parts to Korea in the 60īs) sadly attacked and mostly dismantled since 1976, but where a few old stubborn "whitebeards" stay, until Death (not kidding) does its deed.

So I got a Die Maker (same one which made original Di Marzio pickup dies) make a set for pressing tiny hollow magnets out of ferrite dust, plus another for a half height transformer bobbin so magnets can be floating on the now free area, then visited a local magnet factory who sold me 1 kilo of ferrite dust , enough for about 5000 magnets or >1200 reverb tanks but most important, agreed to run my pressed magnets into the sinterizing oven so crumbly dust became solid magnet.

Having all that, assembly is easy.

As I said, nothing is NASA technology, every single part is very simple and costs peanuts, only problem is that some demand a large minimum order, impossible for the home builder.

FWIW I am currently using my self designed "belton brick" equivalent, works quite well and is inexpensive, my parts cost is 4 or 5 bucks, a mechanical spring reverb woud cost about the same but take much longer to make and assemble, besides the large minimum batch, so nowadays Iīm staying "Digital" .
