micro pdp11/83 power supply

[Waldemar Brodkorb]

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,
 Waldemar
