Thank for all.
On a photo is an output transformer, there is not an input one. I also thought how to fasten him, and found such way. A transformer is very old, there was a sticker "Peridot" but I lost it.
 
To Greg: You will excuse me, if it is possible, explain me the meaning of your post "If I was a betting man I'd guess the output tranny is in that can hanging off the main PCB?"

my english is not so good to understand modern American English.
 
Sure.

kato asked, "No output transformer?"

I was simply saying that I think the transformer is in the round can. :thumb:
 
so now that we have figured out that there is a output transformer, that is non standard to what most of us have done or can find....


How does it sound?

I'm still collecting parts but I'm almost ready to start flipping switches and turning knobs.
 
Yes, the output transformer is toroid. I take them from line output stage of old Hungarian mixer BEAG, an put in the round can from input transformer. I did not order transformers because have a lot of them from old equipment ( such as Tesla, BEAG, Telefunken, Siemens, Marinair and others) I checked up a lot of them as a output and did not see a difference.
 
Hi gevermil.
About soviet (not Russian)transformers I can't say mutch. Because all equipment that was in here was maide in Chekhoslovakia (Tesla), Hungary (BEAG, Mehlabor, etc) GDR (RFT, Vermona) . And very little amount made in SU. I met only one good and suitible for audio transfomer which made by LOMO, I disassemle one, and can make a photo, if you have an interest.
 
Nice work.
