In reply to sho. Hi sho. I used a jensen 1:10 input trans and and edcor 15k:600 half-watt output trans. This resulted in a lot of gain. Enough to use the thing as a mic pre with a tube mic.

Hi Chris, I really enjoyed your Federal 864 clone article.
Your build notes helped me alot, thank you very very much.
I was thinking my next project would be this EQ.
Wonder you are kind enough to add some hints to pick trans.
I know you are fan of Edcor, did you use those? what about input? Again thank you for all those info.

Hi Matth. I did finish it, shortly after I wrote that follow up. It worked great, although it had way too much gain (around 40 db). It sold almost immediately so i was never able to post any audio clips of it. It’s happily employed now with a busy producer and it has found its way onto many records!

I’ll be interested in hearing how this turns out if you come back to it one day. It looks like a build I can probably manage. Thanks for posting it.
