Another good place to buy is Hayseedhamfestco.com.  They will make up  an 
exact replacement for you.  Not the cheapest place but they do great  work if 
you want to keep your S-77 original.  They may be closed for a  couple of 
weeks in memory of the passing of one of their employees.
 
I go along with the use of an isolation transformer when working with this  
radio. Note that a "Variac" is not an isolation transformer.  The best bet  
is a properly installed 3 wire cord set.  Not original, but the safest way  
to go.

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 ?
