The 355's are a piece of cake. You can do it with DC and a voltmeter.


Hmmm. I tried it with an ohmmeter and didn't get what I expected.
Resistance increased to around 100 ohms and stayed there from around
60 dB up.

So, if I put 5VDC across one center pin and ground, I should be
reading voltages to ground at the other pin that correspond to the dB
setting on the dial?
