Forgot to mention, the tubulars can be
replaced with modern mylar, polyester or
polypropylene tubulars or
(overkill) orange-drops. AES or radiodaze
or any number of on-line vendors have
them. The yellow poly tubulars are cheap
and reliable and easy to work with.
The capacitance values will not likely be
exactly the same as the originals,
but within 10% or so is fine. Err on the high
side for electolytics.

Another fine source for caps is Dave & Babylyn Cantelon
at www.justradios.com. They also have schematics for
some US, Canadian and European radios, you might ask them
if they have one for your radio.
