It never crossed my mind because I made wrong assumptioms..   I have qrp lab's qrx on 30 meters that runs 24/7, every 30 minutes on wspr. That runs on bs170. 

I'm learning.

Transmitting WSPR will run the PA flat out for 2 minutes, with the standard heatsinks I am not surprised they blew.
I run a small fan near the heatsinks.
