[Drake] R-4A 1st oscillator transistor

I think I need a new 2N3394 oscillator transistor for my R-4A.  The set 
will receive using the FS-4 synthesizer, but not with the internal 
oscillator.  The cable I was using for connection to the FS-4 has a 
crystal housing on the R-4 end of a coax cable which plugs into the 
crystal socket deck at the rear of the R-4A.  I note that neither side 
of the crystal is grounded in the R-4A's schematic, but it gets 
grounded when I plug in the FS-4, so perhaps that took out the 
transistor.

Does anyone know of a source for the 2N3394, or a good substitute.  I'm 
not absolutely sure this is the problem, so any other comments or 
suggestions are welcomed.

Thanks in advance for any help,

KB8BKU, Darryl
