Replacements for Discontinued Finals
Many 2-way radios were made with
bipolar transistors that have been
discontinued.
This includes many of the popular cb radios. There
are still
lots of these transistors stockpiled in
various places, but the supply is
diminishing. Many
CB radios use a 2SC1969, 2SC2078, 2SC2312 and
2SC2166
as the final. These transistors have not
been made in over 2 years. A suitable
replacement
had to be found. there are a number of other
transistors that
will work in that circuit with a
few changes to the circuit. We have a MOSFET
device
made by International Rectifier that requires very
little modification
to the circuit and produces far
more output. One nice advantage to the
mosfet is
that with a little more DC voltage applied to the
unit - even more
power is produced. At near 15volts
it produces about 40 watts or even more.
Below
14volts not much power increase is obtained. Most
autos provide
14.4 - 14.8vdc while the engine is
running. The kits listed below have all
the required parts
and instructions on how to install them.
Some
soldering is required.

Just Added!!! Add 50 watts to your radio's
output!!!
Installs in just 20 minutes!
