Bob, that is both very discouraging and encouraging. I'm discouraged that we both had a very similar problem with our Ameritron amps right out of the box. However, it is encouraging that Ameritron repaired your amp, and you haven't had any more trouble with it since. Did you ever find out what the problem was? Did it shut down like I described mine did?

Ron,
The same thing happened to me when I fired up by brand new ALS1300. When I got to 1000 watts, the amp completely shut down and I had only had the amp on the air for 5 minutes. Ameritron did fix the amp and I have had no more problems with it.
