Signal Generator

[Joey Voltage]

A lot of times I am looking for a lost signal. Signal goes in but it won;t come out the other end. Often as not, in this go/no-go search, I just use hum as a test signal. A small screwdriver touched to a tube grid usualy gives more than enough "test signal" level for go/no-go.

I learned that trick from you many years ago, very useful, and I use a cheap metronome, or guitar tuner with a 440 pitch for that.

Yep, signals are everywhere. I really only need a signal generator if I am doing something specific.
