You have lots of gain, and you don't need a lot of watts to drive them. Okay some where I heard that the FCC has a 15 db maximum gain standard that you should not exceed.
But if you are lighting up the sky with Giga-watts on 11 meters what do you care about a 15 db rule?
The component count should be lower and I think you should be able to get a clean signal out of it.
I had a car stereo amplifier that had Darlington transistors and big transformers and it sounded great.
It was a KRACO PBS-90 and it would run you out of the truck no matter how loud you like it. I used this truck in the oil fields of South Texas and when we would be cleaning our service vehicles my doors were open and we rocked out while cleaning. It could drown out the sound of a power washer with no problem!
I'm sorry I digress, the point being hostile environment, rugged use and no failures.
So why not use Darlingtons?
