The standby switch in my Jet City JCA2112RC seems to have crapped out. It felt like it was stuck when I tried to turn it off, and didn't feel like the normal click. The amp gets no sound now no matter what (replaced all the tubes and kept trying, tested the speaker using another head). The standby toggle is a DPDT being used as a DPST. One side of it will not turn on, but the other will (tested with the continuity function on my VOM). So here's my question: can I use a Carling 0822R switch to replace it? I have one that came as the power toggle on my Fender Blues Jr (I replaced it with a BillM mod off-standby-on toggle switch; the original switch is a DPST that was used on the mains). The Jet City switch has an odd amperage rating on it, not only because the numbers are so high, but also because the 250V figure is not double the 125V. It says "15A 125V, 20A 250V." The Carling switch from the Fender (and all of the DPST standby toggle replacement switches at AntiqueElectronicSupply) is rated "3A 250VAC, 6A 125VAC." The Jet City amp is the combo/reverb version of the JCA20. Solid state rectifier. Two heavy red wires coming off the PT go to this standby switch, two slightly thinner red wires go to the PCB so I assume this switch is before the rectifier. So do I really need a switch that's rated (or labeled at least) for 20A 250V? Somehow the Carling 3A 250V, 6A 125V switch gives me more confidence.
