Power switch on Ampeg V4 staying "on"

bassdie · #1 11-08-2011, 06:29 AM

So after practice yesterday I go to switch off my amp and... the switch wouldn't stay "down" or "off", it just switches back up to the "on" position.

So... is this an issue with V4's or do I just need to replace the switch?

PS: I have a gig on friday and saturday... how would one suggest I move forward? And DIY would have to be EASY as hell... I have no experience with working on amps.

Not uncommon with the V4 and V4B. Many that are still in service have replacement switches in them. If you don't want to replace yours, go to the local hardware store and buy a cheap power strip with an on/off switch.

Power switches are easy repair jobs, it's a $5 part and probably about 30 minutes of bench time tops. Until you can get it in for repair, as Craig said, you can go the short cut route of using a power strip with a switch. That will serve the same basic purpose.

Make sure the switch didn't get a little loose and rotate enough to ground out. I've had that happen on my BT-15 before and it wouldn't shut off because of it.

Either way, it's an easy fix.

One easy thing you could try yourself is laying the unplugged amp on its back and spraying some Caig Deoxit(-w/lube) in through the little gap around the toggle, then operate the switch back and forth to clean and lube the switches inner contacts. I wouldnt be surprised if it got your power switch working again.
