Peavey Cs-800 Pwr. Amp

dstx144 · 21st January 2006, 12:58 PM

I'm looking at a Cs -800 and the L&R relays are toggling back and forth when you first turn it on, then gradually stopping and acting normal. What does this sound like? I've rplaced all Capacitors in the protection circuit. I don't have the Manual. Anybody have a tip or a copie of manual?

Are both relays acting that way?
Is that with no signal applied? This would indicate a problem in the power supply. What's the condition of the main capacitors?

This is with no signal.
The main caps check out O.K.
This was first giving to me initially with the problem occuring when being driven and with a 4 ohm load. I did not see anything out of the ordinary and gave it back. Then a few weeks later it was brought back with this problem.

I'd like to know if both channel relays act the same.

They are independant of each other. If I had a manual I suppose I could troubleshoot it to a component level. Does anybody have a copy of a manual??

I'll see what I can scan for you.
It won't be a manual, I only have the schematic.

Before i start scanning, is it the CS800, CS800X or CS800S?

Since you have replaced the caps in the protection circuit I assume you checked the cap in the relay circuit also? Checked for a DC offset problem also?

It is the CS-800. I have checked the DC offset while the relays are toggling back and forth also when they finally calm down. There appears to be nothing out of the ordinary. It will act normaly as soon as the relays stop this syncopated chatter. I have not replaced the caps in the relay circuit.

Schematic should be in your mailbox.
Keep us posted.
