Alexandre,

I would be interested in having a copy of that schematic. Would it be possible to post a copy?

Cheers,
DaveD

Hi there Dave! I believe you CANNOT PLUG ANYTING into a TM-50x mainframe
before checking it. BTW, I think I can create a small tool that you plug in
each slot and tests everything (transistors, etc). There is a test-plug-in
schematic by Tektronix, but I could live with something smaller.

I don't remember the exact replacement for the transistor, I BELIEVE the
MJE2955 is the "used" one.

Hope you get well!
