Maybe swap the LHS with the RHS speaker wires.
If the bad channel moves then swap the interconnects LHS with RHS.
If the bad channel stays put, then it is you speaker.
PrimaLuna tube amp issue
Aloha,
I just received by mail a used PrimaLuna Dialogue Premium HO Integrated amp. I hooked it up and it sounded great but after about 45 minutes of listening, the right channel disappeared after a quiet pop. I have swapped out speaker wires, cables...no effect. No bad tube lights come on. Left channel plays fine. Headphone only has left channel as well. It was running a little hot, but not excessively so. Any thoughts...
Bummer way to start with a new/used piece of equipment....sigh.
Thanks for your help in advance.
Michael
