Hya folks I recently built a Mccurdy mic pre with Sowter 9045 input tran but no output tran just 2 resistors & two capacitors, just to try it, and it sounded good.
I since ordered a 8650 output tran 9: 1 I think,have added this to the circuit & now I have loads of distortion ?
Brian Sowter mentioned that his transformer doesn't like DC something? off set was it? & that I may have to put a balancing pot on the cathodes I think?
Cant get hold of Brian at the mo, can anyone give me any ideas as to could this be why I have distortion? and how about this pot?
Im still green & want to learn.
here's the schematic..
