Did you tested with headphones?
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

@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). |
