[BC] FM10K

[Bob Groome]

One more thought; in the FM-10H and FM-10H, the PA tube socket was modified at the factory, may be the same in the 'K'. If so, check the factory to see what they did. Fred Anderson was the engineer who came up with the needed mod of the socket (engineer at Harris who may be retired) for WRNA to solve an efficient problem there. 

Don't think the IPA socket was modified, but don't remember as it's been a few years. The screen by pass caps were a failure problem, though.

Good luck,
