This guy has to be first issue power supply. Currently powering a C28 body and it's got some mains hum. So I suspect that I'm going to have to switch out some of these ancient capacitors.

Unfortunately, they are quite large and have screw bases which are held in by a nut on the other side of the mounting panel. They are all Siemens brand. Here's a few pics of what I'm up against.

The two smaller guys are dual value.

Anyone know what caps that would fit the bill?

Check with Antique Radio Supply in the US.
They have new can capacitors in single and multi-section varieties.
Finding screw base models will be next to impossible.
I have not had any luck in locating these unless you want to buy used and take your chances.
You'll probably have to get the matching twist lock mounts for any replacements.
Looks as if you have two, two section caps and several single section.
 
Thanks Mike,

I'll take a look at ARS and see what they have.

I may have no choice but to hollow out the cans and stick some smaller caps inside the empty cans.
