Sudden change in PAS sound (recent rebuild)




Hi Peter, this is indeed with both high level and phono inputs. The boards are modified with bass/treble/loudness/scratch/tape all deleted. Also the 510k and 63k (i think that's right) resistors were removed/jumpered for use with my 100k sensitivity Adcom GFA535.

And all that has been great for the past week since those major mods. It's only in the past day that this has started.

One other thing: all my 12AX7s are now microphonic! They weren't before, and I even tried another set that I know to be good and those are picking up microphonics as well.
