I installed another like variable across the existing one and tied it to the bandswitch button that is in use when the final band switch is in the 160 meter position. When in 160 it adds the variable and when switched to 80 it is eliminated from the circuit. That is the top most button on the switch. I use a variable however a fixed cap can be used but you will have limited tuning range.
Makes the circuit able to tune into 50 ohms provided you run full plate voltage on the final according to the manual. I use mine on an Inverted L that is ~165 ft. with a series cap to make the antenna a 50 ohm load.
