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

I have the exact same problem, @whacky How exactly did you locate the fuse, take it out? Where did you buy the new fuses? My apologies, I am doing this for the first time. I opened the bottom plate per Upscale Audio’s instructions, I was able to locate the mains fuse but that’s clearly not the problem. Would appreciate any details on how to locate and replace the left channel fuse.

 

Best,
