[Elecraft] Killed the KPA500 :)

[Michael Walker]

Knowing what I did while transmitting at 100 watts of msk144, I’m surprised the damage isn’t worse. 

The protection circuits did the best they could of. 

If you own any amp, you always need to be aware of the risk. I would never rely  on the automation to 100% protected any amp. 

If you are worried about your amplifier and anyway I highly recommend you have checklist handy every time you turn it on and change Bands. Never depend on the protection circuits. 

I know I’m preaching to the choir too many people, however it is imperative you understand exactly how your amp works, how it’s wired, and how it interfaces with any HF radio.
