I have this magnavox amp and I am trying to use it for guitar. Tho it sounds pretty good as is for music, it sounded bad for guitar. I would like to try and improve it somehow. Do you guys have any suggestions?
The first thing I did was clip the negative feedback wire in such a way that I could easily add a switch later.This one thing has made it sound much better and now I am excited about the thought of stereo guitar effects! Next I would like to make the pentode a triode by connecting pins nine and seven to see how that sounds. One question, does that kind of global negative feedback reduce the output impedance? Triode strapping reduces output impedance because of the local feedback within the tube right? So would triode strapping + no negative feedback = pentode + negative feedback here?
Another thought was to use a different nine pin output tube, Maybe a 6s4, or even a 6fd7 to add a gain stage. So far it doesn't seem to need more gain and it is very loud as is but maybe it will need more gain in triode mode, I didn't try it yet. I'm trying to go for the most even order harmonic distortion possible and the least amount odd, hence the idea for the triode conversion. I appreciate any help thanks, Austin
