It is a TNT 600HD amp. I am sure, by the advertised output, it probably teeters on the edge of meltdown during normal operation. So SWR needs to be very low. I am guessing that is why it smoked. The SWR was 1.6 with the amp on, and I need to get it down. I thought that would be safe enough, though not ideal, and I was wrong. When it gets back from repair, I am also backing off the input a bit below the spec. The few less watts output won't be measureable anyway.
