[Collins] 75S3 PROBLEM

[Ed - K9EW]

I have a 75S3 with a raspy-sounding audio tone when receiving CW.  It looks
like it must be from the 4.4Vpp of ripple on the B+ line, so that means
replacing the triple-electrolytic C59.  (I've already replaced the other
electrolytics in the hope that one of them may be the culprit, but the
raspy CW note persists.)  It looks like a tedious job to replace it, so I'm
wondering if someone knows of an easier way to do this than removing
several parts just to get to the terminals of C59.

Do you replace C59 with three discrete electrolytics?  Where do you put
them / how do you mount them?

Or can you rebuild C59?

Or, is there a direct replacement for C59?

Thanks in advance for any suggestions.
