I think you should search for a reset button, beware you loose probably all settings

i dont mean peavey but rcf725 amplifier problem

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.

peavey 5150 II has low humming sound but still plays and sounds pretty good...should i re-tube it?

Hi...
Is the first set "stereo" settings and the 2nd set "surround" settings?
If so that may mean that the surround speakers arent all connected right.

You should consider a microphone with more power to get the volume you need. I can personally recommend the CAD C195 Cardoid Condensor microphone. It has great output. The only downsidefor most people is that they don't have phantom power. This is what gives the mic its boost. In order to get the most out of any micrphone, you need to have a preamp, an equilizer, and an output. The output is your PA system that drumbanger mentioned. 

But since you are using a Peavey, here is my strong recommendation. Get a mini preamp, and hook it up to your Peavey. You can use a Behringer 2mic mixing board for your preamp. It's small, and it can sit right on top of the Peavey.

CAD C195

The reason why I suggest the two-mic XENYX 802 and not the 1 channel 502, is that the 1 channel doesn't have phantom power.

In order to connect the XENYX to your Peavey, this is all you need. You can get one at radio shack for pretty cheap.
