[R-390] Antenna trim repair

[Stan Gammons]

I had one that was like that.  I tried to remove the pin with a drift 
punch but was never able to remove it.  Ended up replacing the entire 
assembly with a part from another RF deck. In the end that RF deck 
turned out to have other odd problems, so I replaced it.

Good luck.

The antenna trim on my 390a is intermittent as the knob is turned it acts like the capacitor contacts need a cleaning real bad. The gear on the capacitor shaft is pinned on I'm not quite sure how to remove the pin, maybe drill out the pin ouch! Why the heck did they pin this gear on seems like two set screws with loctite would have worked just fine.
