Hi All,

I acquired an R-390, that I thought was complete. As it turns out, it
is missing the Coupler "washer" that would fit between the back of the
tuner assembly and the crystal-oscillator. Does anyone have one of
these available, or at least can advise me as to the correct part
name. Wasn't sure if this part
is a "oldham coupler", or something of the sort.
Thanks, Dan
