Weird they went for a third party first instead of going straight for warranty service.

Do they have a spare transmitter? I would hope they would...

It's a pity RF transistors are so fragile...

With a sufficiently bad impedance miss-match it is quite possible to have very high voltages coming back down the feed line, this tends to be what causes damage in a high vswr reflected RF scenario.
