Hi all,
After resolving a few issues with my Crack + Speedball build, it worked well for several months. This week I suddenly started experiencing loud popping in the right channel after the unit has been on for ~10 to 20 minutes. It starts as a soft rustling that builds in volume until it finally discharges with a loud "pop," and then goes quiet. Again, I only hear this distortion in the right channel, including the building static sounds. So far I have tried swapping both tubes, disconnecting the source, and tightening the screws that hold everything to the plate. Are there any other suggestions about what to do next?
Thanks,
Karl
