Switching pops

[rreiser]

Two channel amp pops when I switch channels. The switch uses 9 volts. I tried a .1 cap and it helped a little . Id' like to get rid of more if not all the popping when switching. Thanks for any help. Russ

What type of switching? Relays? Is there a reversed bias diode across the coil to prevent flyback?

If it clicks during only one of the transistions you can likely put in a muting circuit using a sprinkling of solid state (gasp) components. Let me know what you have and I can design something for you.

4.7uf to 10uf cap should get rid of most of it. YMMV
