The modified amp is spoken for. I still have the unmodified amps. These 
are very easy to modify. It can be done with standard hand tools. The 
bias keying circuit can be found by searching google for STF2520A. This 
is a lower power amp but the modification is the same or you can use a 
relay. I would be happy to provide details and photos.
