I have one of these preamps that I built in a cigar box. I turn it on with a regular DPDT toggle switch. When I turn it on, my stereo makes a big nasty POP sound, so I usually turn it on with the volume down. However, I want to make a circuit that automatically turns it on when my turntable tonearm un-docks. So I have to do something about the pop.
What causes the pop? Would an RC circuit on the power rails, so the voltage slowly builds up to the rail voltage, make it better, or is it something else?
