I restored a pair of General Radio Unit Power Supplies, a 1203-A and a 1203-B.
They both needed new power cords.
This is the 1203-A, with tag-board construction.
This is the 1203-B.
I got to use my Chinese-imitation Heyco pliers on the line cord strain reliefs. They work well enough, especially for the price.
There’s not much to go wrong with these supplies. The filter capacitor is likely to be the only troublesome component.
This was a good excuse to put to use the HP 428A Clip-on Milliammeter that I bought from Chuck Ochs at one of the NEARC meets.
At 70 volts, ...
… the filter cap (in parallel with the 120 KΩ bleeder) was pulling 16 mA. Definitely leaky.
So it was time to take photos ...
… and start disconnecting the filter caps ...
… so that I could re-stuff them.
I removed the cans, cut them open, re-stuffed them, and reinstalled them. I’ll have to go back and take some photos of the finished job.
