Knight KN-755 schematic & vintage audio transformer Test Site

I don't know about that, but FWIW I used to own the KA-95 decades ago, which used EL34s. The transformers in the amp were low profile, similar to what is seen in the KN-755. So they were custom wound. 

Are you trying to duplicate this amp or part of it?

I was budding on the KN0775 but it already has 16 bids with 5 days to go. So I started bidding a Knight KN-925 with fire bids and 4 days to go. If I win it I will change out all coupling caps to Russian k40Y-9 and also rebuild the PEC with discrete components for the tone controls. Best tubes I ever heard are GE 6BQ5 and JJ E83CC. At 15 watts per channel it makes enough power.

I meant Knight KN-928
