Yes.  If the TS-450 does not have an amplifier control relay, like the 
TS-440, it Very "probably" can Not.  The fix is to convert to positive 
relay control voltage, like the SB-220, and install high speed switching 
to make the old amplifier compatible with newer transceivers.  .

This does not take care of the hotswitching problem.

True, Pete.  Hopefully, they would read the instruction manual first.  
Sorry, folks.
