I'm replacing the power switch on a TL-922A amplifier and I need to replace the ceramic capacitor soldered to it as well.  Can anyone with this amp advise me what the value of this capacitor is?  Does anyone have this capacitor available for sale?  Tnx, Steve  spz1@att.net

It's probably there to de-arc the contacts. .1 @ 500 would be fine.

The original cap (C66) is 4700pF at 500VAC.  Using a cap rated for DC, I'd pick one rated 1500 or 2000VDC.

Thanks fellas,  I was able to get a 4700pF @ 1000 v. from Mouser Electronics.
I appreciate the help.

I have one other question.  If anyone has physical access to viewing that power switch, can you confirm that there is a total of 7 wires connected to it plus the capacitor?  That would be a big help to me.  Thanks again.
