I am looking at a 10 Meter mobile amp with (2) 6KV6A or 6JG6A tubes. I know
these are originally sweep tubes. The input SWR is over 3:1 and I'm thinking
that a resistor has been replaced by a wire jumper. There is no series
resistance or capacitance between the input and tubes. Adding a 25 Ohm
resistor drops the input SWR to 1.5:1 or lower. So what kind of power output
should I see on AM and SSB without harming the tubes?
