[Icom] IC751A Logic Unit

[Tony Hwang]

Hi,
My 765 never had PSU problem but then I did pre-emptive strike. Replaced
all the caps and reinforced all the solder joints. Most of cheap
switching power supply trouble is caused by capacitor. Also the Molex
connector. Treated them with liquid gold, and tightened them pins.
