Troubleshoot and Repair an ICOM IC-746 - YouTube - I repaired my IC-7400 antenna tuner motor with help from this video


To insure that IC151 not fail from ESD or heat - Solder one capacitor 10 - 20 uF parallel with C156 and place heatsink over IC151. The

heatsink can be fix to chassi with epoxy.


To insure no problem with DRV Board Q1/Q2 (ALC Jumping) - Place one heatsink over Q1 and onother over Q2. Respective

heatsink can be fix with existing screw.
