Greg,
Wow! Thanks very much for that wealth of information on the old Kenpro. My old unit still works fine, but some of the hardware is rusted pretty bad. The G550 hardware looks identical so I may be in luck.
I also need the terminal cover, but I doubt Yaesu has it since they don't use that type of wiring configuration anymore. Need to find some generic cover that fits.
Thanks again Greg

Unless you have access to a local machine shop and machinist,
your only source for these Japanese manufactured parts is Yaesu USA.
SOME of the KR-500 parts may be identical (common) to the current production Yaesu G-550 elevation rotator.
Yaesu purchased the Kenpro Company which originated these designs.
The individual azimuth and elevation rotators were KR-400 and KR-500.
Later came the KR-5400, the KR-5400-A/B and the KR-5600-A/B.
[i]After the purchase, Yaesu eventually changed these prefix designations to "G" from the earlier "KR".

All,
Can anyone tell me if the mounting hardware on the Yaesu G-550 is the same as the old Kenpro KR-500? Anyone other than Yaesu selling parts for these units?
Thanks,
