Thanks for the info,
I did not think I would find a replacement, but it was worth a shot.
The R-390 fellows cut open the cans and replace the caps, but the 75S can
has a much smaller diameter. Still, it is worth trying.
I'll let you know if I find caps that will fit in the can.

Jim...
You can empty out the original can and install three nice brand new single
section caps from MOUSER inside and end up with something better than
original when done. There are a couple of websites outlining the process out
there. Not real difficult.....
IMHO, Most of the caps you will find will be NOS and have laid around for
years. The price will be high and the condition in question.
