Aesthetix Io strange behaviour

This morning, my Io won't play music. The only thing I hear is scratching/popping noise when I turn the volume controls. Same thing in both channels. Tried changing cables, etc, but no change. Anyone has an idea? The unit has played beautifully especially since I got a full tube replacement from Aesthetix some years ago. I've heard nothing to indicate a coming breakdown. The lights on the unit come on OK, and as far as I can see, the tubes light up normally too. Strange.

Best to call Glenn at Aesthetix. He will know.

Thank you, I got no answer but left a message.
The problem is specific, perhaps the cure also?
I've changed power supply tubes and fuses - no help.
Obviously there is power out, since I hear these noises in the speakers when I turn the volume knobs, varying with their level. Only no music, the input does not get through. I tried just now once more with the aux input (to cd player), just to be sure it is not some analog player or riaa problem. But the result is the same.
(For the record, the Io has mainly been problem-free for me).

OK, cleared up. A local electronics repair shop was able to do it. They found "a defect regulator V1 in the power supply and changed the V1 tube". Reason for failure not known, may have been the fault of the tube. Whatever the case, music is back - great.

i think is good to send to local unless they replaced same parts,
My IO is still on repair almost a month now.
