| There are a lot of radios that use the EPT-3600 14-B board and it is probably the most used board in the industry to date. All of the DX-Galaxy radios such as the Galaxy 33, Galaxy 44, Galaxy 55, Galaxy 66, Galaxy73, Galaxy 77, Galaxy 88, and Galaxy 99 use this board. All of the early Mirages that correspond to the Galaxy's model for model and the NorthStars also used the EPT-3600-14-B pc board. The Varage, some of the Ranger units and most of the Connex radios use it. |

Before doing the following modification
be CERTAIN that the radio is in excellant working order. If there are ANY modulation
inhancement modifications currently installed, be sure and remove them as they WILL clash with the NPC/RC Modification
Common modifications are:
- The insertion of a diode in series with R-238
- A diode simply IN PLACE OF R-238,
- A 220K resistor in place of R-238,
- A double-diode-double-resistor mod at the C-189 & R-240 location.
This is commonly called the Christmas tree mod. When removing this
mod, replace R-240 with a 560 Ohm, 1/4 watt resistor.

| >>>>>>>>>>>>>>>>>>>>>NOTE:<<<<<<<<<<<<<<<<<<<<<
There is NOTHING about this modification that can jeprodize ANY specification
in your radio. Do NOT compromise the mod by leaving out any of the steps. The most common mistake made is to leave out the red wire on the bottom. (RWOB)
The RWOB is NOT there for the purpose of so-called "volting the finals". The prupose of the RWOB is to keep the moduation transistor from running to hot and as a by-product of this step, the voltage is raised on the finals to the same voltage that it would have if it were operated on SSB. If you were to raise the final voltage to 20 volts, it still WOULD NOT BLOW the final/s as long as you follow the procedure exactly.
