So far, so good...  Time owned: 3 to 6 months
I've owned this amplifier a relatively short time and so far it seems to be performing very well. It produces 600 watts CW drive on most all bands although I wasn't able to get it to tune up at all on 10 meters. This amplifier is very easy to tune and quite forgiving, especially with its fast acting GOP circuit. The only issue I've noticed is a premature firing of the gas clamp tubes which was more pronounced when the unit was new and only occurred within several minutes of start up. The problem is also more noticeable at low load settings. However, once drive is applied, things seem to settle down and there are no other issues. Highly recommended.

Great Amplifier  Time owned: more than 12 months
I've owned my Ameritron AL-811HD for about 18 months. This amplifier has worked great. I've received many good signal reports with it, and I have nothing but complements to make on the amplifier. Support from Ameritron has also been great for my few questions.
