This Zetagi model TM 535 tuner was modified to Dr. Bare's book specifications with the exception of the smaller balun. The small internal balun has been re-wrapped with 22 guage Telon wire.
I cut a hole in the top of the case and added a 4" DC fan over the balun. I also cut a small hole on the right side to create an air flow out over the large induction coil.
The induction coil was modified to Jim Bare's recent posting to the Rife-List for the Zetagi tuner. The top end of the induction coil was brought level with the top most
rung of the coil. The bottom end was already level with the bottom part of the coil.
The guage wires were kept from lying on the metal floor of the case.
A 12 volt DC light was added to the guage meters for easy viewing.
My induction selector is set to "K" .
I still have to initially adjust both transmitter and antenna dials when starting up the device; but I don't have to tune the device once the frequencies are running after the inital setting.
I usually get SWR's (Standing Wave Reflected) of 1.15 or less.
Power forward usually runs from 150 - 100 watts on the linear's medium power.
Connect the coaxial cable from the RTX jack on the tuner to the ANT jack on the linear amplifier.
The flatwire from one end of the plasma tube copper sleeve connects to the black terminal which is linked to the top red terminal. The lower red terminal connects to the second flatwire to the opposite copper sleeve on the plasma tube. The yellow terminal is the ground.
