Nolan's R-390A/URR Master Capacitor List
Revision 0.4a BETA (01/13/02)
This list is still "BETA". As a result has NOT been checked as closely
for errors as usual. Please drop me a message if I left anything out or
if you spot an error and I'll correct it and re-post. Thanks, nolan

(1) This is the bathtub style capacitor mounted below the line
filter on the rear panel. It is NOT an oil filled paper cap
even though it looks like one. Watch the polarity.

(4) This is the stud mounted oil filled capacitor located on the
top side of the chassis next to V201, the 6DC6.
(5) Not used on early receivers. C256 is used to silence hash/static
from HR202 Crystal Oven. Less expensive CDE polyester should work
fine at this location.

(x) value depends on mod level of IF deck. I'll add details later...
(2) Oil filled metal can paper capacitor mounted to top side of
chassis next to chassis harness connector.
(3) Blocking cap for mechanical filters. Recommend working voltage
of 600VDC or higher to help decrease the chance of frying the
mechanical filters due to failure of C553. This is not a good
location to use a cheap replacement capacitor.

(7) Also known as "the capacitor that rots off". Leaks sulfuric acid
when the seals fail. Watch the polarity when replacing.
