This
modification kit contains all the parts you need to install MOSFETs in
place of the original bipolar transistors in your Cobra 2000. This kit
will replace the driver and final with MOSFETs. Detailed instructions
are included. The final transistor installed in most CB and many Amateur
radios were discontinued and are rapidly diminishing. They are hard to
find and very pricey. If your final has been damaged now is the time to
make the conversion to a MOSFET. All high powered devices are changing
to MOSFETs. They will be widely available for many years to come. In
most cases they produce more power and in all cases they give more
modulation. On most radios the time to make the change is about 1 hour.
You need only some basic electronics knowledge and good soldering
skills. Don't be fooled by those cheap kits. These are not ERF or IRF devices. These unmarked Fairchild MOSFETS are very rugged and forgiving. They were designed for the medical imaging industry and are very reliable and may forgive YOUR mistakes.
