Hi,
as my first post here I would like to ask a question about a DEC
correspondent terminal with a broken power supply.
due to a shorted capacitor in the output stage, a whole train of parts
has failed, including some diodes, a coil and the main switching
transistor in TO-3 case. that is the part with a strange partnumber:
A8250
151278200
I suspect that the 8250 is a manufacturing date and the long number a
internal DEC number, but what sould be put in its place. i was thinking
about just using a irf840 mosfet, but i have no idea as if this would work.
any thoughts (or maybe some schematic?)
