75 watt Original Equipment Final Amplifier Section with high performance low pass filter for Magnum transceivers (and many others)
 

The RFX75 is a new RF section for Magnum 10 Meter Amateur transceivers. The RFX75 can be bought as a replacement part. It's is a low cost solution to replace bad RF driver and final output stages in other 10 Meter Amateur transceivers that used obsolete / discontinued transistors.
 

This module is being used in many types of radios for power increase of 75W.
(Output varies from radio to radio. It depends on the radios driver stage. Anywhere from 60W to 100W)
