Many of the 75A-2 and 75A-3 receivers have brown colored capacitors instead of black like the 75A-4. Of course, the 75A-1 used bathtub capacitors. Although bathtub capacitors have lasted longer than other paper capacitors, they are going bad on a regular basis these days and I just replace all of them with modern capacitors.

Others have remarked that the modern capacitors are so much better than the oldies. When I restored Collins S-lines and A series radios, the first
thing advised was to replace the 'green' tubulars and paper capacitors. It made a great difference in their performance, so all of the BBODs are
going to be replaced in my SP600. Thanks for your comments, Glen.
