[R-390] R-390 Caps

[Tom Frobase]

I have been replacing my own for quite some time, it really only takes
a few minutes.

First I cut the can just above the crimp, I use a band saw but a hack
saw works fine.  I the cut the aluminum wires at the top of the pin
where they are crimped.  Setting the socket aside,

I put the top of the capacitor in a vise, slowly heating it with a
propane tourch, once the binder is soft I remove the guts by grabbing
the remaining wires with a pair of pliers.  I then file the top of the
pins flat and drill holes, slightly larger than the tap size for a
2-56 screw in the top of the pins, Once the holes are drilled I screw
2-56 brass screws in to the socket until they are bound tightly.

The rest is easy, solder the replacement caps to the brass screws and
replace the cover.  I then run a bead of gray epoxy around the seam.

I have purchased replacement cap's from Mouser and Digikey both supply
a small form factor version that fits easily back into the original
can.  I have been doing the same for about 20 years and I don't know
of one ever failing ... 73, tom, N3LLL
