Message-ID: <Pine.SUN.3.95.970414060734.21644A-100000@spike>

None of my few reference books around here provide any info on
can-type caps, oddly enough.

I'm trying to clean up an old, homebrew power, 235v supply purchased
at a hamfest. It uses an electrolytic filter capacitor in an aluminum
can.  It has 4 pins (3 are used) and are unmarked. There are 4 tabs on
the edges to hold the cap in place, with 1 tab having a braid soldered
to it (ground). The side of the cap says:

ZENITH

20    475v  (cut off circle icon)
40    300v  (square icon)
100   50v   (triangle icon)
80    25v   (dash icon)

Part number 22-2223

This can is soldered directly to the circuit below.  I'd like to
unsolder it and test it before firing up this circuit.

1.  Which pins are what values?  They're unmarked.
2.  Do the values on the side of the can correspond to the pins?
3.  What would be good modern substitutes?

Thanks!
