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,
Tony - K2MO
