Multiple KPA-500's with Combiner

RLVZ
The "combiner" idea is an interesting concept for the KPA-500.  
"Combiners" are very common in solid-state broadcast transmitters and  one of the
major advantages is "redundantcy".  If you had 3 KPA-500's run  thru a combiner
and running 1,500 watts output... even if one died then you'd  still have
1,000 watts output.  For serious contesting work,
the "combiner" sounds like a terrific idea.  3 KPA-500's x $2,000  = $6,000
which is close to what a single 1,500 watt solid-state amp is  likely to
cost and with the multiple
KPA-500's you'd have the big advantage in that you're still on-the-air  
with almost full power even if one KPA-500 fails.

Joe,

Why not stack 4 KPA500's and use a  combiner!!!
