The only thing I have to contribute it that you have to beat the snot out of a small ameritron to get the advertised power. If you want a 800 watt amp I think you may have buyers remorse after the second set of tubes.
I would skip anything with 811s or 572b tubes. The AL80b is a much better amp and will make an easy 750 pep. You can get a nice used one for the price of a new 811H.
Every time I call out CQ I get a pile up.
I've got a problem with my 811H. Every time I call out CQ I get a pile up. Lol I've learned if your not ready to talk, don't use the amp. I'm totally impressed with this amp. Had a QSO on 40m yesterday that lasted 20 minutes, and the amp was nice and cool putting out 600 watts. This is what I was hoping for, and I'm getting what I asked for. I do tend to stay on 1 band way longer than I used to, because now I have to adjust the tuner, and the amp every band change. I guess that's one reason to buy a solid state amp, that follows your transceiver. It will cost 3 times more however. So for now I'm going Old school with amp and manual roller inducter tuner, with a high tech radio. I'm diggin it.
