Did you reach out to the person you bought the amp from? Does it have any known issues?
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
