[R-390] r-391 off freq.

[Doug Collins]

Hi!, new to the group. I have a R-391 that I acquired in 1976 still in the
crate. Still in mint cond.. Ever since "new", it has been 8-10kc off freq.
It zero beats perfectly on all WWV freqs. with bfo on"0". But if you change 
bands it's off freq. I have moved vfo coupler to adjust but that throws it
off on WWV by 8kc to high.
I swapped a r-390 vfo with same result. Change the RF deck, same thing.
Change crystal osc., again same problem.
180v b+ is fine. All tubes are good. I know these radios pretty well but
this has always stumped me and 
several others. This my main receiver but I also have 2 R-390 non A's. Any
ideas????? Thanx, Doug  Ka4swt
