I’m using a Darkvoice 336SE Tube amp that recently began only outputting sound through one channel, even if it’s turned off. I can literally unplug the amp and sound will still transmit through one channel. I’ve already disassembled it to see if anything was obviously damaged, but everything looked normal. Short of breaking out a multimeter and testing each individual component, what are my next steps here?
Check for resistance of the inputs to the output. It should read quite high.
