resistor & cap pair matching
That is an interesting read Tangent. My own DMM is a cheap velleman with what looks like 2000 counts of resolution. I gave up trying to match resistors because under most ranges it's totally not up to the task. But now I am wondering if I can use my limited understanding of Ohm's law to help my...- Aguirre

It is only when I adjust the volume control and for about 20 seconds after that the DC voltage spikes and slowly comes back down. This is with...- Aguirre
