Subject: Replacement Diode
(Sending again because I sent it from the "wrong" account, apologies if
this
gets duplicated)
The saga of my broken PDP11/24 PSU (H7140) continues. I have now found a
shorted diode and need to find a suitable replacement. On the printset it
is
described as "D 672 TR=14NS PIV=60V SI".
What would be a suitable replacement?
There is a local Maplin that would be open today that has this one:
http://www.maplin.co.uk/switching-diode-46386, would that be suitable?
Regards
Rob
Just a bit more information in case it is helpful or relevant. The failed
diode is D26 on p88 of the H7140 printset, which you can find here:

Thanks again.
