I have a Texas Star DX500 (non variable) amp that I have been running for about 6 years now, trouble free. Recently, the amplfier would throw the SWR's off the scale when turned on. I have checked all grounds, changed coax jumpers and coax to antenna, checked the antenna mount, etc, and found no issues. I also bought a new meter, and it reads high as well. Took the amp to a local tech, and he saw the same thing on his bench.
He does not have a spectrum analyzer, but said it looked...
