I’ve had the top plate of contemplating... to be frank I’m kinda worried about pulling the whole thing apart and risk fucking up a good functioning amp.
I was planning around 10mA as well, my PSU is ~450V with a SumR 500VA transformer, amps are running A1968’s.
One thing would make the job a lot easier is paralleling over 180 ohm resistors, would this be a problem Kevin or Spritzer?
