Retubing a Crate Palamino V8
I'm almost positive I need to retube my Crate V8, five watt, amp. It hums fairly loudly and crackles sometimes. It does not hum, however when you pull out the guitar plug from the input, it is silent.
I bought a new Monster Cable and it hums loudly with that too. When I smack on the side or top of the amp the hum either changes pitch, reduces in volume, increases, or goes away.
I can easily remove the chasis, as I am mechanically inclined and have tools, so this is not a problem.
Do I need to bias the Crate Palamino V8? I can't find my digital tester but would buy a new one if I could bias the amp myself.
So, does the amp require biasing, and, can I do it myself?
Any advice, shared expertise from someone with a V8, or other ideas will be greatly appreciated.
Right now that is my favorite amp, using a Digitech RP350 into it to get tones the amp would not normally be able to produce with its three knobs only. Great amp though.
Thanks in advance,
