MS contracted a company somewhere on the east coast.
I had my V.2 repaired for the right channel. It was linked to the subpar assembly/build QC.
Mine is 10 years old. Still playing, but now has a wonky right toggle switch(gain)
I demoed the Foz side by side with a few very popular,comparably priced, even a bit more costly brands, and thought it wasn't blown away by any of them
You need to find a competent tech who can ad lib since no schematic is available.
Sad, because I did a side by side with a few comparable tube units(popular brands) and thought the Foz wasn't blown away by any of them,just different.
I'm eyeing the new Prima Luna to match my PL amp.
