re: TRM-40B

Still have one, though it's down for yet another re-cap and general rebuild. Low & line-level stages long since replaced the germanium transistors with silicon with greatly reduced noise; this time around, though, it may be time to jack up the box (which is a very convenient size) and slide in practically everything new. We'll see. 14WPC was optimistic - significant distortion sets in beyond 8-10 - but that was typical for the time.

re: TRM-40B

Hi! Could you elaborate on which transistors you replaces and with which ones, and also if you had to rebias them? Thanks!
