Output transformer suggestions for solid state Pultec

[letterbeacon]

I am going to build a solid state pultec clone using the 2520 DOA as the gain make-up stage.

I have the HS56 for the input, but don't have a second one for the output and I wondered what the options were, or what people would recommend.

The original used an HS56 wired in reverse, using the 250r tap so it's a 2:1 step up.

I was thinking the UTC A20 - anyone have any experience with that? Does anyone recommend any others?

It doesn't have to be vintage, I'm happy to use a modern transformer too.

Thanks.

1:1.55 step-up.
In my opinion, should have been a 1:2 unless one thinks the sound of original Pultec SS is perfection.

sonically a dog.
and I am a UTC lover, the big LS-30's aren't much better.

Does anyone recommend any others?

fed from "zero" impedance, and please, lets not quibble as to what constitutes exactly 0 ohms,
the UTC A-22 get rave reviews.

any of the suitable Edcors, step-up.

Thanks, I'll look into the Edcors and also maybe Carnhill as I'm based in the UK.

Interesting that you say the A20 is a dog - it seems to get good reviews on here, especially used in Pultec circuits.
