Our lock pre-amp doesn't seem to have enough gain.  This makes our samples
impossible to lock without saturating the lock.  I can't find the RF parts
needed to repair and Varian wants a fortune for the pre-amp and has the
subcomponent gain section (953050-02) we need backordered.  Does anyone have
a surplus VXR300, Unity 300 or XL300 lock pre-amp (00-953065-00) they  would
be willing to part with?

We are always looking for surplus VXR parts and cards for this machine which
gets harder and harder to keep running as it ages.

Thanks,
