Re: Hum pot in DHT preamp ???

Hey Dave,
The side which is more negative is usually referenced
to ground in my amps.In case of fixed bias, this is directly connected to ground.
In my 801 preamp and poweramps, which use the 'filament bias'
approach, the more negative side is connected to the
bias resistor which goes to groundThomas
