Help! I have a rhythmic popping coming through my speakers when my DAC wth a valve analogue output stage is switched on. I have established a couple of things this evening:
1) The rhythmic popping issue is limited to one channel.2) The rhythmic popping starts off slowly, every two or three seconds, and speeds up to twice a second.3) it is unlikely to be a faulty valve. I have swapped the valves with a spare set I have and the problem still persists. Any ideas on on what this might be would be very helpful.
