Now I see it, and I agree. Sharp Eye!
That being said, it is still...unsafe. The chassis ground connection should be a DEDICATED connection to earth ground without having
any other responsibility. Like holding down a PCB! Oy vey.
Oh, and how about the UNTWISTED AC wire coursing itself near the RCA input? Is it too hard to twist? Will fingers fall off? Or did we run out of wire on a $3K product? Flip that PS board 180 degrees, twist the AC wiring and minimize the distance!
I don't care what the PSRR is of this design, but there are ways to build electronics in a
safe and repeatable manner. Moreover, what use is an amp if it isn't reliable? Does it matter what it looks like or costs at that point when its...um....CAPUT?!
Has anybody heard of a bonafide engineer called
Leo Ayzenshtat who designs fantastic GaN based designs, called the Starkrimson? Hellooooo?
End rant...
Thanks,
