Has anyone had any luck getting into the antenna trim can to clean the cap? 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.
