I turned on my stereomour II and immediately saw arcing in the left 2A3 tube and loud feedback/crackling out of the left speaker. I built and have owned this amp for a couple years with no issues. Is this just a tube failure? Wanted to reach out to the community prior to ordering a new tube. I did read a similar post that seems to indicate that this is the case. Just being cautious. Thanks for any feedback.
 
It could indeed be a tube problem. The best course of action is to replace the tube and check the DC voltages on that specific tube socket to ensure all is well.
 
Paul, replaced the tube and all good. checked the DC voltage terminal 1 365v, terminal 2 395v, 21, 22,23,24 were 58v. Please close out, thanks again
