While this amplifier will run more than 1200 watts PEP output, linearity will suffer. Ameritron recommends running no more than 1200 watts peak power for maximum linearity, where this amplifier will have comparable IM performance to the best vacuum tube linear amplifiers.
An interesting turn of events last nite...
I was testing the ALS-1300 into a dummy load at various drive levels on each band, preparing a drive/output table for this review. When I tested the amp at 25 watts on 10 meters (about 500 watts output) the amp started tripping into protection mode. Then when I tested it on 10 meters with a little less than 100 watts drive, the amp and power supply shut down and now it won't power on.
I'm in contact with the folks at Ameritron and they are going to send another amp and take a look at this one to determine what might have caused this problem. I was really digging this amp until this issue, so I'll be interested to see if I can replicate the problem on another unit, or if things will continue on without issue.
More to come...
Did Ameritron ever tell you what the problem was?
I used to think that Ameritron put out good high quality equipment...but after 2 amps in a row that were found to be defective I am beginning to wonder just how many units has been sent out to folks with those problems
I hope they get this sorted out for you Moleculo
