[R-390] Dial off 50KHz?

I put the original RF section back in after finding the cap I left out 
that makes the calib osc work. So now the calib osc works. But I'm not 
sure what I did, other than I put the other RF section I had in, it 
didn't work, so I removed it and after I fixed the cap in the old RF 
section, now the dial is off by 50KHz reading low. Actual 10.1 reads 
10.05 so the 10M band shows up below 10.1. I always turn the PTO and 
dial to far left like the book says and I'm wondering if I got it off 
somehow? Should I try to turn the PTO maybe 1/2 a turn, I'm not sure 
what 50KHz is in relation to a half turn on the PTO? I guess I could 
figure it out. At least the calibrator is working now. Maybe I can get 
rid of this thing.

I've found it easiest to turn the RX upside down to get the Oldham 
coupler and spring back in. And loosen up the PTO. I can get the RF 
section in and out in about a half hour now with all the cables and screws.
