So I have an old E-mu Proteus 2 rackmount synth that I got off Kijiji, but since plugging it in after my move, I discovered the audio output is frequently dropping out, most audible on sustained samples.

I'm suspecting the DAC's capacitors are toast, since I don't notice any sort of sign of power fluctuation (the LED panel stays lit for example) or data issue (the MIDI input light flashes in time with all events logged) but I know a few people I follow are tech heads too so can anyone weigh in with a second opinion?
