If you have “spare” or extra 12AU7 tubes, try to spot which of the left three 12AU7 tubes is not lit up and replace that (power off and after 5 minutes of course). If you don’t have spares, I would swap the left 3 12AU7s with the right. Taking note if numbered 1-6 from left to right, swap 1 and 6, 2 and 5, 3 and 4. See if now the Right channel doesn’t work. Like what BrianNguyen said, turn off all the lights and see which tube isn’t lit up on the left side. Good luck brother. I have the same exact PL Dialogue Premium and love my amp.
Left Channel Out Primaluna Dialogue Premium
Hey folks. So I turned on the stereo last night ready to listen to some tunes when it was clear there was no volume at all coming from the left speaker. Right channel sounds just fine. I did some speaker/cable/source switching and swapping and determined it was the integrated amp. It’s a Primaluna Dialogue Premium which is the predecessor to the EVO 300.
I swapped out all the tubes, still nothing. Did some research and stumbled on some info regarding the fuse. I can replace that today but if it was the main fuse, wouldn't both channels be out?
I came across a similar thread on here from @whacky who mentioned a left and right channel fuse.
”There are separate fuses for the right and left channel. Not just the main fuse. they are contained on inside a small fuse holder on the left and right side after you open up the underneath.”
Problem is, I can’t seem to locate an internal left or right fuse. Nor can I locate any kind of PL schematic that shows where this fuse might be. I have a message into Upscale and maybe they can point me in the right direction but I thought I would reach out to all the fine folks here for some assistance.
Any other thoughts as to what the problem might be? If it is a left channel fuse, where is that guy located? Thanks for your help!

@paulcreed unfortunately this model only has one main fuse so I can think that’s the problem. @pangeek thank you for the good wishes and yes, it’s an amazing amp! I really love it! Sad it might be out of commission for a short time but hopefully not long. I will try your suggestion later tonight when I’m home again. I do have four spare 12AU7 tubes so maybe I can narrow down the issue with them.
