Peavey Audio Players & Recorders - Recent Questions, Troubleshooting & Support

If your Sanpera 1 pedal has suddenly stopped looping on your Peavey Viper 1 amp, it's possible that there's a hardware or internal issue. It's recommended to contact Peavey customer support or a professional technician to diagnose and resolve the problem.

You mean the KB A300 if it has a Mic input with XLR. No, there is no crossover in it as there is only one 15" speaker and it doesn't need it.

Sorry we have no parts here or any way to locate them.

are you the original owner, with a receipt? This amp has a 5 year warranty. If not take it to a shop, we can fix them, they are damn complicated for an amp...black magic inside.

I am assuming this is a new unit. Take a 9V battery and momentarily connect it across the speaker wire, it must not be connected to the amp. If it makes a noise that indicates that the speaker is probably OK, if not you found your problem. You may want to take to the store where you bought it for help.

The Peavey PV-10 is an unpowered mixer. Simply bypass it with a signal source to troubleshoot its operation. The problem is elsewhere.

You might have disturbed a connector that feeds power, making it come loose. Turn the unit off unplug it from the mains and recheck all connections on ALL the boards, not just the one you replaced.

2 Channel Peavey CS-800 Amp (800 Watts) ... Peavey CS-800x 800 Watt PA Stereo power Amplifier. The Part in question Q4025P is an alternistor. Two SCRs back to back that may have shorted out if it is not working.

Either there is a bad ground or the power supply has blown a diode or capacitor.

You have likely almost but not totally fried a voice coil in your speaker. Most speakers get cooked from underpowering, not from being overdriven. What are the speakers rated for and what are you driving them with?

Check to make sure the WIDEST blade of the AC power plug is actually the GROUND (as in "not HOT") in the new location!

I am thinking what if the power amp has a separate power supply to the pre-amp. If it does then something in that is causing the problem. If it doesn't then it's something on the power amp board. Perhaps a voltage regulator. If the power amp is a single IC job replace it. Another possible cause is if the volume control is done via a single IC. If that has gone it would cause the strange things that are happening. One thing is certain it's something that both channels pass through the device that is faulty or it effects both channels.
