Check out 73 magazine, July 1970. K1CLL built an amp using 811As in
push-pull. I actually duplicated the amp and it worked as stated. He claimed
400 watts out on CW. I didn't have a wattmeter at the time but it was a
barn-burner.

807s. In the old days I've see low-band radios that used the 807 up to 40
mHz or so on FM.
