If you have a multimeter, you can check the fuse(s) for continuity.
No Output from left channel on Primaluna Dialogue HP
Was wondering to query the hive mind before I sat down and tried to figure this one out myself.
See if anyone had thoughts on how to go about resolving the issue.
I lost output from the left channel on my Primaluna Dialogue Premium HP Integrated the other day.
I hadn't turned the amp on since Hurricane Irma came through. One night during Irma, I had a few power surges that happened. I was worried the tube amp would suffer, despite having it connected to a power conditioner, so I switched my amplification to an older SS amp. Turned the tube amp off, and haven't turned it back on since.
Well, I finally had time to reconnect everything last night only to realize the left channel has zero output. Right channel working fine. I meticulously identified the amplifier as the cause.
-I'm not getting any red lights for bad tubes. Despite this, I changed out almost all tubes to confirm. Still no output.
Anyone have any thoughts as to the source? Fuse blown? Something worse?
Any fixes I should investigate?
Current tubes available are 8 KT150 power tubes, 6 Cifte signal tubes, and all the original primaluna tubes.
Thanks

In the event you don't have an owners manual here's a link to get the one you need http://www.primaluna-usa.com/owners-manuals/ |
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 |
