Ok, So LOW RF power on AM is set for 2.5 to 4 Watt setting and you're not getting there from the current Driver and Final Install...


Did you or someone you know, install MOSFET before?


This radio may have been a BIPOLAR board (set up and parts support for it)...

This Graphic shows MOSFET parts and DIODES installed

- but DRIVER and FINAL Numbers are SANDED off


So you have to choose your poison - the more we know what has been done to the radio - the better off we ALL are for being there to help you get thru this.
