power/standby in one switch?

[acorkos]

is there a way to wire a 3-position toggle switch as both a main power on/off switch and standby/operate switch? thanks for your replies....

Unless you get a special 2-pole switch that's off-on-on, you can wire a more standard 2-pole on-off-on so that in the lower position it's in standby, and quickly flip it all the way up to run the amp. I've seen some old Univox amps (IIRC) with a switch like this.

the Ampeg is a good design, of course few switches are rated to handle the high DC B+ voltage; there will be arcing and a need to eventually replace but they can last a long time if a beefy one is used:

I've done it that way before. Not exactly elegant, but it works when real estate is limited.

These work for me. Look in the switches heading, under Parts.
