I forgot to mention that it is the ARR SP432VDG model.

Hi All,
I was monitoring some passes while mobile today, and amidst all of the
confusion of messing with coax and frequencies,
You have blown it--If you are not a handy tech. - Send it back to ARR
and they have a flat fee for repairs. Check with them on the
internet.

Thanks for the responses everyone. And Dee, no, I am not a handy tech -
obviously! I transmitted probably 2-3 times through it using 35w, 1-2
second each, then it blew. Like you, Mark, I am a little surprised it blew
so quickly, but oh well.
Thanks!

Another thing that may have gone is the RF sensing circuit that is
probably set for 25w max. RF switched preamps are more susceptible
to burn-out as they rely on fast switching of the preamp bypass
circuit. Even a few milliseconds delay will allow enough RF energy
to zap the delicate GasFet
to remember not to transmit 35w through the preamp.
