Update to my R&S NGB 32 / 10 repair.
Finally I succeeded. Yeah!

Output voltage: -0.6 ... 36.8V - needs adjustment
Output current: not tested yet, need a proper load. All I have actually are two 10 Ohm / 100W resistors
Here is, what I have replaced:

I have no idea what the previous owner did, but with his "repair" attempt he'd managed to toast the 2N3773 and the 2N3583
This is a nice comparison of these old Roederstein capacitors (yellow, 3300µF / 63V) with a new 3300µF / 80V from RND (this is the brand of reichelt):

And these are the mil-spec 1N823A, looking very nice in their red cases

I think, I'll write a repair report. I have no idea what this guy had thought when he replaced those 8A slow blow fuses with 10A slow blow ones and blew them as well.

This damaged the power transistors which otherwise wouldn't have happen.
Moron.
