Section 7 Theory of Operation and
Troubleshooting

Power Supply Unit

The PSU has the job of converting the 12V DC Input (8-16V
range) to 29.5V for the MOSFET transistor drains. Why do we
do that? Several reasons, the state of the battery no longer
affects operation until all useful energy in the battery is
expended. Operating the MOSFETs at a higher voltage
overcomes IR (current and resistance) losses in a 12V system.
The higher the voltage the more the gain is possible. Why stop
at 35W? Why not 100W? Well have you tried lugging around
the heavy car battery on your back pack trip? When you boost
your 2.5W signal up to 40W, you go from2.5 to 5 to 10 to 20
to 40W. Each time you double you increase your received
signal by 1 S-Unit. A signal increase from in the noise to a S4
means your signal is readable. Your power pack to do this can
be a 7AH Gel Cell or some of the newer light weight Lithium
Ion battery packs. I used to fabricate 25, 50, 75 and 100WH
battery packs from harvested cells in DEWALT power packs.
But that is another story. The point is that you can operate
from a light weight power source and only be down 1 or 2 S-
units from a 100W rig. Many can testify how effective this is.

Power Input

The 12V is input through the 30A contacts of the Power Pole
connectors. There is a right way and a wrong way of putting
the little plastic pieces together to insure your connectors are
polarized correctly. The industry has a certain way of joining

the pieces together to be compatible with everybody else.
Make sure you set up your jack to receive plugs that are
configured according to the drawing below.

Housings should be

mated according to the

diagram above, viewing

from the contact side

(opposite the wire side),

tongue down, hood up,

RED on the LEFT,

BLACK on the RIGHT.

Also notice the 3/32-

inch-diameter roll pin,

1/4 inch long, is used to

keep the housings from

sliding apart

Reverse Voltage Protection

No one can stop a lightning bolt from wrecking havoc but we
attempt it with our reverse polarity diode and thermal circuit
breaker. If you ever apply voltage in reverse, there will be
enough time to fuse the reverse protection diode into a lump of
metal before the thermal circuit breaker from kicking in to open
the circuit. It will do its job however and save the other
components in the amp. The thermal circuit breaker is the tan
colored tab that is mounted by its tips to the circuit board. Why
