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.

hi, yes, I swapped all tubes from right to left channel. No impact. But,before I swapped I noticed a very faint amount of sound from left speaker at higher volume. Basically, still at square 1....

 

thanks, 

Michael

Hello all, thanks for all the feedback. I reached out to previous owner and he suggested, as a number of you have, to touch base with upscale audio. I have made contact and they are walking me through a series of steps via email to close in on the problem. At this point, we are at the thorough check of tube point and will likely progress from there. If all these tests fail, I suspect he may have me take a look inside to see if there is any obvious damage. 

If anything significant pops up may return to this tread. Thanks again...
