UA 176 output transformer?

[Alva Goldbook]

I'm working on a varimu compressor design and would like to use the same kind of output transformer that's on the UA 176. Does anyone know if anyone is making reproductions of them?

IIRC Reichenbach (sp?) may have been a supplier back then. So, check with Cinemag nowadays.

SOWTER 1285

Cinemag is making them for Retro and they won't sell the same design to third parties

I think I saw them on the Sowter website.

Better get my coffee in me, Beatnik gave you the part number.

What was the name of the Polish company doing transformers too Beatnik?

When I asked him about this 2 years ago on this thread
https://groupdiy.com/threads/utm-industry-audio-transformers-from-poland-eu.79307/page-14

His response was "It's too complicated with so many primary taps. No plans right now. Maybe in the future. I'm sorry."

Maybe it's far enough in the future to ask him again.......

CJ can you tell what was the core material in the original transformer ?

There they are

Core material is probably silicon steel since this us butt stacked which reduces the permeability by a factor of about 10 to 20 so using alloy would be a waste. And the DC in the primary would be another reason. And the turns count us high enough to give the required amount of inductance with regular steel.
