G,3V 2A

Fig, 1, Schematic of the tripler.

Coupled to the plate tank closest to the ground end of L4 and adjusted for maximum output using a number 47 pilot bulb or whatever you may have.

B plus is applied 3 inches from the center of the 7 pf per section butterfly. On one of the few built so far, maximum out put was acquired with the B plus 3/4 inches from the center of the condenser. So don't be afraid to play with this adjustment,

Tune-Up procedure

Apply 5 watts of drive to the input and turn CI until the pilot light lights. Adjust L5 for maximum output. Connect an Antenna to the output. (I built the beam described by Hoisington in 73, December 1964. Note; !i you want to get all elements on it, get a 14 foot boom; then call CQ and fight your way through all the QRM,)

\ 'sing the audio from the driver, you will be able to work the boys; but they will all tell you it is mushy. What 1 did was take an old record player audio amplifier and convert it to a modulator, i his may be a good idea in case there are any official observers in your neighborhood.

By the way, the Output of this gem is 4Yi watts measured on a Bird watt meter\
