Took my AL-80B to Starkville,MS so Rob and Mike at Ameritron could solve e
the high vswr on the 15 and 20M input circuits. The amp was also a tad low
power at 650 cw. Once the 3-500Z got replaced the input vswr tweaked down
to spec as did the output power about 850cw. The old tube was an Amperex
and the new one a Taylor. Now with 2800 on the plate under load it easily
sails past the 1KW pep mark on my YS-60 meter on all bands.
Just sharing this ..thought it was interesting the "input" problem was the
"output" tube.
