Trash  Time owned: more than 12 months
I have had 3 switching power supply failures now, and in the last repair Ameritron replaced the complete power supply at an internal warranty cost of over $1000. Now the power supply is overheating in the start up mode -- it starts OK from a cold start, but if I turn off amp I have to wait over 10 minutes before the power supply will restart. On prior returns the tech missed the intermittant receive and I was sent a new antenna relay board that I installed my self -- I can replace bad parts with good parts. The tech also missed the binding multi-meter switch that required repositioning board behind the front panel. Now with having to deal with the slow power supply start-up I leave it on most of the time. Recently, the amplifier will stop working after about 30 minutes and cut out on
a PAB (amplifier power imbalance) fault. I tried to check the final PA transistors bias and it looks way different between the two amplifier strips. So, I am packing it up again for one last time before I ask for my money back under Texas deceptive trade practices act.
Meanwhile I am using my 10 year old Alpha 99 that works just fine. I know how to operate and tune
amplifiers. Trash boxes (ALS-1300) don't belong in my shack. 73 Jim, retired engineer, K5YZS
