RE: Stabilize Analog Milliammeter

Posted by shermanr@prw.net on February 7, 2012 at 09:35:32:
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.
