Has there been anything written about repair of the ZERO ADJ., when it does not seem to release the clutch to zero the kHZ dial setting. I am off from 1 to 3 kHZ over the full range of 0 to 32 MHz which is probably more than just the zero adjust but I cannot do even the basic adjustment on any calibration point from top to bottom. Looking down inside the front panel, I can see shaft turning and as it gets close to the stop point turning clockwise, I can see what I assume is the clutch plate just barely moving. I have looked through many of the instruction manuals I have but seen nothing about repairing the ZERO ADJ. I am guessing that someone out there has repaired this at some point.
