New 70s Hybrid project (colour scheme?)

Very cool! I'd never heard of that. Does it make much of a difference? I'll have to mod my chassis, which I'd gladly do if it's worth it!

Hi Joost,

look at the attached pic. The hum pot is the brass one on the back of the Brown amp next to the AC inlet socket.

It is a simple 100 Ohm balance pot from CTS. Middle lug to ground, CW and CCW go to one half of the heater wiring each.

Cheers,

Electron

I looked around at the USA suppliers and Digikey has the CTS wirewound, 5w, 100R hum balance pot for $3.64

Almost no current flows in the CT so the pot is not seeing much either.

THanks Chris, that is what I thought I remembered but wanted to make sure.
