Question about Peavey 6505+ 112 Combo Amp Combo
The amp has a constant buzz when I turn it on. It is still playable but irritating. Even when everything is turned down, no guitar plugged in it still has a constant buzz.
Sounds like a bad power supply filter cap...the buzz you're hearing is the 60 cycles hum that filter caps reduce or (hopefully) eliminate altogether. It may also be related to the tubes but finding the bad one will require some work. Any friends have this same amp? If so, try swapping one tube at a time and see if you get lucky. If this amp is new take it back ASAP as it is a manufacturing defect.

The preamp section has a problem. It could be anything in the preamp but is OFTEN the input jack itself. They take a lot of abuse.
Also the insert jack contacts that forward the preamp to the power amp if no external FX are used can go bad.
Additional things are circuit board cracks caused by rough handling and also controls that have had the knobs mashed in which can destroy the potentiometers they are connected to.

Sorry but your post did not provide enough info. Are you having a problem with the volume control. Do you need a wiring diagram. What model Peavey bass do you have. For instance, the Peavey bass I have has active electronics ans requires a 9 volt transistor radio battery to power them.

I don't believe there is a power "outlet" on this, only an "inlet".
Usually the inlet will have a lead, often green, that goes to the chassis.
There will usually be two other wires, often black and white that connect to the other two pins.
From the back of the connector, with the center pin tied to the grenn wire of the triangle lower, the pin to the right should be the white and the pin to the left is the black wire

my vypyr 75 JUST did what you were talking about. From what I'm researching this has happened before and it's the fuze which is soldered to the circuit board. I'm taking it to the store I bought it from so they can fix it. I see you posted your problem a long time ago but I hope this helps someone new that it happens to.
