[R-390] R-3909(non A) - ten turn stop question

[R390rcvr@aol.com]

Good evening all!

A rather sad R-390 followed me home last night. One of the oddities is that 
it won't go onto band one. The megacycle shaft hits the ten turn stop before 
it will allow the gearing to drop into the detent. Its close, but won't quite 
make it. It seems to go a bit too far on the high end of the range.

I have looked through the manual for this radio, and the R-390A, and although 
the stops are discussed, how to adjust them isn't. I am not going to do a 
complete gear train dismantle at this point, and wonder it just that 
adjustment can be done, without upsetting synchronization?

There is a clamp on the gear driven by the MC shaft, so perhaps by locking 
the dial lock, loosening that clamp, and rotating the shaft just enough to 
allow it to drop into the detent will work? The radio is working, kind of, so 
I would like to not disturb too much until I have a good baseline performance 
check.

Thanks

Randy Stout
