The PSU is dead. I know about the fire catching wires and they where not
the problem. I inspected the PSU and I get the usual 300VDC input at the
actual PSU PCB, but the PSU does not start. As SM-PSUs are black magic
for me, I gave it to a co-worker that is familar with this kind of
magic. If he can repair it and he can get a KA640 based VAX for me I
will give him one of my two 11/73 CPU, RAM, disk, ... so he can build
his own PDP 11 and I don't have to bother with that SM-PSU magic. :-)
