I may be oversimplifying here, but maybe it's unnecessary to go to all this
trouble. The figure mentioned was 1 dB of loss at 1500W, which amounts to
around 300W by my calculations.

1. Can the balun in this amp dissipate 300W?
2. Do QRO baluns have a history of burning up?

These are not rhetorical questions, and I honestly don't know the answer to
either question. But knowing the answers to these questions might eliminate
the need to dig a lot deeper.
