Bassman aa864 guitar channel hum
Posted: 30 Sep 2017, 07:27
Hello,
I've a Bassman aa864 and the guitar channel make hum thru the speaker and I have'nt any guitar sound. The hum interacts with the volumen pot, if I pull of the V3 valve the hum disapear. The bass channel Works well.
I tried to change valves, but the hum persist.
Any idea?
Thanks.
