Title: Simple Audio Modifications for the Globe Scout 680 Post by: Steve - K4HX on December 16, 2012, 12:28:13 PM Simple Audio Modifications for the Globe Scout 680 AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
This mod replaces the 6U8 with a 12AX7 and improves the frequency response a little by getting rid of the Couplates. See attached schematic. |
