Hey guys, I’m hoping for some insight and perhaps advice concerning my SE84UFO. As of late it simply stops working after a short while. I hear a slight pop or something like it and then .. no sound. This has happened a few times now, after several hours of play and after only a few minutes as well. I’ve checked all other components (including modem and router), after which, I swapped the amp out with another. The system works as expected after the swap.

The tubes were replaced 2 months ago, are all working, and seated properly. I didn’t notice any odd behavior or sound prior to this either. I’m perplexed.

I haven’t heard back from Steve yet so I thought I’d ask the community. Any clues? Thank you gentlemen.

Thanks Geno. I reinserted the amp the same thing is occurring. I need to open it up I suppose, which is nerve-wrecking for me. I hope to speak to Steve soon as well. Fortunately, I have plenty of gear in storage to keep the music playing but I already miss my SE84UFO.

Just a follow-up .. it was the power tube(s). Paradise has been restored!

BTW, I'm such a newbie and instead of replacing the power tubes 1 at a time I replaced both, so I don't honestly know if it was 1 or both tubes. I will check at a later date.

Thanks again for your help Geno.
