Title: high-pass filter for 5f1 champ
Post by: isaac_teller on July 18, 2020, 02:10:48 pm

Hello. I want to add a variable high-pass filter to a standard 5f1 champ. Where would I insert it in the circuit(I assume after the first triode stage) and what would it look like (component values). Thank you.

convert the preamp to a 5F2 and see if you like that
