RE: Trying to find the problem

I work on a lot of equipment, one thing that I use quite a bit is a cheap pair of speakers, you can pick some up at yard sale, goodwill etc for about $10. Connect the speakers to your amps, nothing on the input of the amp. Use a small screw driver or a wire, touch the inner conductor or the input, one channel at a time. Use your body as a source, meaning touch your finger to the wire or small screw driver shaft, you will get a loud rude sound out of the speaker telling you that amp channel works. You can also just plug a cable into the input and touch the other end center conductor. Do same test on the other channel. If you get sound out of both, then connect preamp to amp, select a line level input like DAC and do the same thing you are now testing the preamp. If that works both channels you have a DAC problem or whatever you normally feed the preamp.
