I've managed to find out a little more about the two missing components
on my PDP-8/Ms power supply and alas they look most vital!
One is a DEC 1110714 bridge rectifier and the other is a MJ900
transistor. I think I've sourced the MJ900 but can't find anywhere
stocking the 1110714.
Does anyone know an alternative non-DEC part number for the rectifier?
Many thanks,
Toby

I've just started the rebuild of one of my
PDP-8/Ms. This is an early
machine with the power supply mounted on the left of the chassis.
One potential problem I am slightly concerned about is that the front
two power transistors have been desoldered and removed. Does anyone know
if these are a vital part of the PSU and if so what the part numbers are
so I can try to source replacements?
You can see a picture here http://www.pdp8.co.uk/ (enlarged view here

If anyone else has a PSU of this type, could they take the opportunity
to take a few pictures for me. Would be really useful to have another
reference source for the rebuild.
All the best,
Toby
