You may want to contact Denis Kohlhagen, at Butler Winding. IF this is for the
preservation of an HP terminal in the museum, they may wish to assist in
rebuild/rewinding that flyback. There are US firms that can perform this work,
and publicity of preserving history is desired by some
Yay! Congrats Josh!

Thanks, all, for the responses! The way it measures out makes it look like
it may be an MJ10006 or similar. I think it's probably ok.
I poked around a bit more this morning and it's looking like part of the
flyback is shorted out -- we have a 2382 at the museum and I popped it open
just now and
The 9816 uses a BUZ45 - might be the same as the 2382?

Forgot to mention, I have a 2382A that works (affectionately known as the
"Munchkin" terminal). I could measure some stuff in mine for comparison if that
could help out.
For the HP curious, the 2382A makes an appearance at the end of one of my
videos:

It is
Can't find it either in any of the X-ref lists I have. As you know already,
1854 are usually NPN transistors, but around these numbers I see mostly
Darlingtons in my collection. So maybe that's what you have, and why the
junctions would test weird.

Hey all --
Got an HP 2382A terminal I'm attempting to resurrect. I get no video, no
heater, no high voltage. What I believe to be the horizontal output
transistor appears to be bad, but I'm not sure if this thing contains
internal diodes that might be throwing off my testing attempts. It's
