Hi,
I started to revive an old Micro PDP11/83 I have for over 12 years
now. It is fully assembled and last time I tried to start the
machine it some kind of started.
My biggest issue at the moment is the power supply.
After the machine is running for a while, let's say 10 minutes and
then when I poweroff, the power supply starts producing a lot of
dense smoke. The smell is very penetrant.
What can I do with the power supply? Do I need to exchange it
completely or just parts of it?
At the moment I removed it from the case like described here:

Thanks in advance for any starting hints,
Thanks to anybody have given a response. (some personal mails).
I successfully reassembled the pdp11 after changing the two blown
filters. We have a small electronic shop in Bonn, which had the
stuff available:

So now I can successfully start and stop the machine.
I am planning the next steps, may be I will ask some more questions
the next days.
best regards
Waldemar
