Those LDMOS are sensible to input power. You must take care not to overshoot them. I own the same amplifier (version 2, as I think the displayed one is also), and I have tortured it with long high power digital transmission time and sometimes bad antennas for a couple of years and never got a problem. Nice to know how to adjust the BIAS... just in case.

Hi George, are you replacing the LDMOS? If you are, can you let me know how you were using the amp when it popped? Thanks and 73 Eric

@@erics.8340 Hello Eric, yes of course. A friend was using FT8 on my Kenwood TS-990 which is an extremely destructive mode on any amp, it's a weak signal mode. Had I known he was going to use The FT8 mode I would have stopped him but in this hobby anything can happen. Be careful who you let DX with your equipment. It's all in fun, I'm just happy I was able to repair it. Best 73 OM de George, W2GSS

I never understood how a fully automatic with built-in antenna tuner can blow a transistor!
