  Dave,

I can't think of any way to do this, or any reason to do so.   I suppose 
one could jam enough on-frequency signal into the VFO input to make 
something come out the antenna socket,  but it's not designed to do 
that, and what would be the point in trying to drive a 6AG7 power 
amplifier that uses plug-in coils?   Some VFOs will put out as much 
power!   The 10A is a heterodyne type exciter that's intended for use 
with an external VFO  which is offset from the desired frequency by plus 
or minus 9 Mhz.

I will add that if the question stems from the 9.0 Mhz crystal being 
missing,  there's nothing sacred about that value, and any crystal in 
that range will work, just alter the VFO frequency to compensate.   9 
Mhz crystals have also become available on eBay for cheap.
