Replacement caps
Your photo does not show the voltage rating on the cap sections. Antique Electronic Supply has some firecrackers but the voltage ratings are only around 160v.

4 individual capacitors mounted to a terminal strip would do it. Two 22uf and two 47uf at whatever the right voltage is. That looks like something with a real power transformer, so you'll probably want 450v caps. What I'd personally do is find yourself a terminal strip with at least 5 terminals to mount to the chassis basically where the old cap was. Cut the wires from the old cap, land them on the terminals, and hang your new capacitors to that. Just watch that you don't land a wire on a grounded mounting tab.

A picture tells a lot. Interesting that it does in fact have a power transformer. Usually, amps and such with power transformers have the can capacitors mounted on the chassis.
I am still amazed at some of the designs that I have never seen before. I have seen thousands of VM amps but not one like this. Pretty cool!

drawing needed
I opened the big cap to see what I am dealing with. While I tried not to destroy the old cap, I need functionality a lot more than keeping everything in stock appearance. Unfortunately, I did not learn anything once I opened up the cap.
My question is: How do I connect 4 new caps to equal the one old cap. As a bottom level hobbyist, I can copy what I am shown, so any crude drawing would be much appreciated.

I am working on something similar- multiple wires, and the common negative "black." I did the strip mounting as suggested- is the black ground here?

The wires from the old cap should be color coded,,, connect a new cap of the correct value to the corresponding wire from the old can... bundle the new cap ground wires together, and connect them to the ground wire from the old can...
As stated previously, try to mount teh new caps, where the old can was, to help eliminate hum/noise...

Appears 30uF is Blue, 16uF Red,,, I assume black is ground, but it can be easily traced and confirmed...
