Vocom became Crescend, Crescend then acquired Milcom which i think was part of Powerwave.

Anyway combining those two amps together to give you a full 200W output will be tricky.
I don't think you would get a full 200W. You would need some kind of combiner that will
keep them both in phase. You may want to keep an eye out for some of those older
Milcom amps on ebay that have been stripped of amp stages with the combiners still
intact in the amp cabinet.
