Occasionally this amplifier will show no grid current with drive
present. As drive is increased the plate voltage drops in a linear
manner. With no RF drive present plate voltage is normal at about
3kv. When operating in this condition the amplifier will show some
output when tuned, typically about 10-20 watts and no more. Prior to
further troubleshooting here does this sound like a familiar issue? The
problem is intermittant in nature.
