i just got ahold of a '74 traynor head, a YGL-3a. anyway, i'm going to try to replace a few things. it hums pretty loud(not buzz, but hum)...there is a fan inside of it and i am wondering it it might be causing it.
there are some gigantic mallory caps inside, look like sticks of dynamite....they seen to have 2 positive leads, so i don't want to get involved with them just yet.
so 3 quick questions:
1)can i simply just disconnect the fan, or would i have to put a resistor or something in line?
2)the rectifier diodes are IN5062; they look....goofy and low tech. should i upgrade these?
3)the tremolo doesn't function at all. i don't know which tube drives it, but could a bad tremolo tube cause a loud hum?
