5E3 Standby Switch Question

[Leif H]

I have used it for a split/shared V1 cathode R/C setup, a bright switch, a half power switch, and a few other things. Before you laugh about the half power switch, I've had a handful of 5E3 customers complain about the amp being too loud for home use and that is why I have implemented it. Attached is a gif file of a cathode biased power section half, quarter and full power switch drawn by a member of the Hoffman amps forum some time ago.

Looking at this, I think I'd like to give it a try. What kind of power rating would you suggest for the 330 & 100k ohm risistors on the switch, with the bias resisors being 520 ohm -5W?

I don't know why you just don't use a conventional standby switch circuit and break the B+ lead from the rectifier cathode(s) to the first filter cap.
Any 2a to 5a SPST switch will work fine.

Bruce does this stby arrangement have a pop? My stby switch is popping, especially when placed IN stby mode. I have it breaking the B+ line.
