- I'm still trying to figure out why I can only get about 600 watts output on 14 MHz from my Henry SS750 amplifier (8 x 2SC2879). I measured the output into the dummy load with various levels of drive,

- Mine has the 2 db attenuator (AT1) in all of the time and the 3 db one (AT2) is switched in on 160, 80, and 40 meters. Not on this test, though I did on the previous test on all bands with 100 watts.

- The spec sheet says 15 db typical, 13 db minimum at 28 MHz. I would expect the gain to be greater at 14 MHz. And I have a 2 x 2SC2879 amplifier, as well as my TS850S which uses 2SC2879s; both of thes
