What to do about my humming amp?

Rob P	What to do about my humming amp? Hi all, I own a peavey TKO115 bass amp (sorry, i'm building a tube replacement at the moment) actually i don't mind it, seems to sound pretty good to me. anyway, the problem I have is that it hums. i've tried quite a lot, and i have found that the hum is in the preamp. (when i plugged a jack into the power amp input, all went dead quiet) i've tried replacing each opamp, with no change in hum. does anyone have any other suggestions, should i maybe start replacing caps? (don't know why that'd create/remove hum) anyway, i've run out of ideas, so any input is much appreciated. thanks, Rob

What to do about my humming amp?

Hi all,

I own a peavey TKO115 bass amp (sorry, i'm building a tube replacement at the moment) actually i don't mind it, seems to sound pretty good to me.

anyway, the problem I have is that it hums. i've tried quite a lot, and i have found that the hum is in the preamp. (when i plugged a jack into the power amp input, all went dead quiet)

i've tried replacing each opamp, with no change in hum. does anyone have any other suggestions, should i maybe start replacing caps? (don't know why that'd create/remove hum)

anyway, i've run out of ideas, so any input is much appreciated.

thanks,
Rob
