Re: Where to install the DO-5 Zener for low hum?

Howard	Re: Where to install the DO-5 Zener for low hum? I installed mine in the left side, facing the back of the amp. This is the smooth (no holes yet) vertical surface on the left side of the chassis adjacent to the PT. In my self built cabinet, there's plenty of clearance there for the nut and it's about as far away from the signal carying part of the circuit as you can get. This leaves me more room on the bottom surface (where the tubes are mounted) for magic mini switches to do things like changing the cathode bypass and coupling cap values, NFB etc.
