[TenTec] Corsair I gone bad!

During testing thru a Bird 43 into a dRAKE 






During testing thru a Bird 43 to a Drake KW dummy load my Corsair decided to quit with a bang like a firecracker and a puff of smoke exiting from the 3/8" hole in the top of the final assembly. The power supply breaker tripped 

After I recovered from this sudden turn of events I discovered that I still had a working transmitte but could only get about 30-45 watts output before the PS breaker tripped at about 14A or so. 

I strongly suspect my Corsair went from a nicely working radio to a "parts unit" in an instant but decided to touch base with those that are more comfortable with the events I've described. What likely went astray in the RF final?
