Can't Stop Humming

Ron · 2006-06-12T17:53:24+00:00

I just bought a rather nice electric guitar kit for a hundred bucksthat came with a 10 watt amplifier. The guitar is pretty nice but theamplifier has a rather nasty hum. I thought it was a vacuum tube ampbut found out it actually has transistors-- or an IC amplifier-- I'mnot sure.The power transformer is pretty close to the circuit and the wires forit were tangled with some of the speaker wires. When I untangled them,the hum disappeared... until I plugged into the jack the guitar cable,then the hum came back. Does anybody have any suggestions for gettingrid of this hum problem?Ron

Just out of curiosity, were the jacks separately mounted to the chasis or were they soldered to the PCB like both the input and headphone jacks in my amplifier are mounted?
