PL HP owner here.
Couple of years ago, similar problem. Its a relay not functioning. Time to strain your back lugging it to the shop.

No Output from left channel on Primaluna Dialogue HP
I'm going to spend some time with the amp tomorrow to finally take a look at things. @imhififan I haven't listened with headphones. If I listen with headphones and it comes through in both channels vs. still has no output via left. What would that tell me? I'll take a look at the fuses. Pull out the multimeter. Does this thing have two fuses? I guess I will figure it out tomorrow. @tablejockey How did your problem present itself? Single channel no output? Power surge? If you don't mind me asking, how much did the repair set you back? I didn't buy the amp from Kevin at Upscale Audio (It was a forum purchase), but I have bought about 1.5-2K worth of tubes from him, so hopefully if I can't figure it out on my own, they wont mind me asking them for help. Warranty on these amps are not transferable correct? Thanks |
@imhififan I haven’t listened with headphones. If I listen with headphones and it comes through in both channels vs. still has no output via left. What would that tell me?If listen with headphones and it comes through in both channels, the preamp section is fine. If listen with headphones and still has no output via left, could be problem from the preamp section or the source. Another way to verify is connect a source with volume control or another preamp via HT bypass (bypass the preamp section). |
whacky-the amp warms up normally, and my left channel was dead. There is a relay that switches "on" after warmup.Presumably connecting to speaker taps. Unless your tech savvy, it's something left to an expert. Mine fortunately was warrantied, I purchased it from Upscale. Kecin can give you an authorized service tech in your area and answer other questions. As mentioned, perhaps you can still listen using the H/T bypass using a source with a volume control. Good luck. |
