Thanks for the tips, Neal.  What seemed to be the problem with getting 
them on 75?  My goal is 3.880 thru 3.890, so I would be very interested 
in any experience you can share.  I am now in the process of 
refurbishing the oscillator board, but I have to wait until the R2 
schematic arrives before I can go much further.
