Large Can Power Caps Compatibility Question

~~~~Out of a 1970s Pioneer SX1250 receiver, 4 capacitors 22000uf 80v 85C Nippon Chemi-con (brand) C E W below logo. Aprox 5 in. tall and 2.5 in. diameter. A couple of these are have what appears to be an overheated area on the center of the bottom between the screw terminals, bubbled and leaked a dark brown goo.

Found 22000 uf 100v, Capacitance Tolerance + 50/- 10 %
Part number 95F4479 at

Are these satisfactory replacements? Seems like a drop in fix, but since I'm not a tech I need your expertise. Thanks in advance.

They look OK to me. The real rating you have to be careful about in Power-Supply (= electrolytic) caps is the max-voltage rating. You NEVER should use an electrolytic cap with a voltage rating LOWER than what was there. (Audiofile-grade film caps are a different story--their rating can safely be exceeded [by maybe 50%] without a problem, altho I'm sure there will me some who disagree with me.)

I think you're OK on these PS caps. Be sure you have the polarity right before screwing/soldering them in.
