I've had the TubeMagic A2 for a little over 3 years with no issues. Last week I started noticing that the left channel was getting quieter and less full (anemic) sounding than the right. I've tested all sources independently and narrowed the issue down to the amp, and switched out both tubes and swapped tube positions with no luck. 
 
The problem affects both the speaker outputs and the headphone jack (right side full, left side weak), however in the case of the headphone jack if I remove the plug halfway so that only the left is making contact, it sounds fine. Gradually pushing the plug in from halfway, the sound in the left channel gets weaker (not linear, in 3 steps. Think: FULL, not as full, weak) until fully plugged in and contact is made on the right channel. Swapping speaker wires only reverses the issue from left to right. 
 
Any ideas?
