OK, thanks. I guess that will be C19 and D27 then? Is there anything in
particular I should check about C19 other than if it's shorted? Having
said that if I was shorted then I would expect much bigger problems.

Yes, it's
the VT100 PSU with the small linear supply for the start-up. I
don't know for sure there is anything wrong with mine as it seems to
work OK. Maybe I'm trying to debug something which isn't actually a
fault? When you've worked on these in the past have you noticed any
components getting hot (particularly R27)?
I will check... I've not got the
printset in fornt of me (and having jsut
come round from a gneral anaesthatic, I do not feel like hunting for it
tongiht...) but if R27 is part of the snubber netowrk, then check the
associated capacitors adn diodes _very_ carefully.
