RE: Stabilize Analog Milliammeter

OK then will simply enjoy the music.
I will give them bias pots a shot of Cailube and test.
The meters dance when the HVAC system compressors kick-in.
The fluctuations probably just make it through the power supply B+ and also the bias voltage.
If I disconnect the amplifiers from the Preamp, the meters settle down but still wiggle a little bit.
And they still jump when the Airconditioners cycle.
Thanks for the advice.
