As I said,
most SMPSU faults are capacitors or power transistors :-)
One problem is obvious:
The big 24000 uF capacitor is missing from one
The value of that capacitor is not _too_ critical. 22000uF would be near
enough, for exampkle.
brick and this brick was repaird bevore. There are
some burned traces on
the PCB that where replaced with wire and solder long ago. Unfortunately
it looks like I will not get time for the PDP-11 this evening too. Some
local computer colectors are making a barbecue. :-)=20
You are lucky to have other local collectors.
