Recently, my Fifty/Fifty got quieter on one side. I thought it was a failed PI tube, but it happened again shortly afterwards and swapping tubes did nothing to help. I have to turn it up to 7 on A to get it to match the level at 1 on B. Of note is that the presence knob seems to do nothing on the quieter channel - it sounds like it has something to do with the negative feedback circuit?
