[R-390] Filter cap replacement question

Barry:

I obtained mine from Digikey, but all the 33uf capacitors appear to be a "standard" size. I got around the size by expoxying two caps together, then expoxying the third on top of the other two thus creating an assembly which I wired to the base. The base-another nightmare! I didn't waste time attempting to solder aluminum wires, instead I drilled out the original wire and drilled/tapped the pins (2/56), inserted brass screws and soldered the assembly to them!

For you guys who are restuffing your R390A's electrolytics, which caps are
you using?  I ordered some from Mouser with the intent of simply installing
them "bare" through the holes in the octal sockets.  Sadly, the octal
sockets in this AF module, though, don't have through hole style sockets;
therefore, I'm planning on using an octal plug.  I have some old cans from
another set I've gutted, but these caps are just about 0.010" in diameter
too large to stuff three of them in the can so I was wondering where you are
getting caps small enough to fit three inside the cans.

I have some old burned-out octal tubes and their bases are a perfect press
fit in the old cans so if I can find small enough caps, this should be a
cake-walk.

Thanks in advance,
