I agree with Dan. I have had my 811H for almost 3 years. I bought it used at
Dayton and use it with my Omni VI. I use the tune button on the Omni and
tune it in low power.(Approx 15 to 20 watts). I can get over 600 watts out
with about 50 watts of drive. It will run 800 watts, but I rarely go over
the 600. I use it on CW and SSB.
Its been a good amp and I have not changed any tubes.
