Hi Scott, I recently finished two S-51s, While there may be places to buy the old style 'can' caps, I leave the original in place, and after disconnecting it, replace each section with a modern electrolytic, under the chassis. MUCH smaller and more reliable.
All the old, waxy caps in these 2 radios failed a leakage test (horribly) at their rated voltage.

Lots of places to buy caps from Mouser, to eBay.....

hello guys wonder if you can give me a little insight
looking to re cap the radio
one of the electrolytic is listed as a 60-20-30 mfd
150 v

if I understand it correctly that means there are 3 caps inside the electrolytic
what do I do buy one of each and twist the leads ? and solder in place

I would also like to know the style of caps to replace the tubular paper's that 
are currently in the
unit .
the problem I am experiancing is a decrease in volumn a station gets tuned in 
and slowly the volumn
goes town
and afte a while it will increase again
it is a gradual change each way
any ideas ?
