It's actually 200 watts, and yes, there are two "final" PA's, each capable
of 100 watts output, that are combined. However, each "fina

Steve,
I have one on the air. I have replaced the stock GE power supplies with
15-volt switchers. They are MUCH lighter and cooler. Plus at 15-volts
you can get over 300 watts output! I sometimes joke that I have more
power lost in my duplexer than most have out of their repeaters
If you wa
Is the combining done externally to the two PA units? If so, you should
be able to split them and keep one as a reserve.
I just picked up a PA that appears was from a similar arrangement. It
had two SO-239's on the heatsink side, both entering the PA compartment.
Inside, there was no driver boa
Its been a while,but from what I remember-no! They use one PA to drive
two more which only have the finals and Wilkinson combiners,so they wont
work stand-alone.Nice find though,I'd use it as is,but prepare to watch
your electric meter spin a lot faster!!! 73,Lee
