[ICOM] IC-765 question

[Tony Hwang]

Hi,
The very first thing to check is the solder joints for the fuse(?) on 
the PSU.
It looks like a piece of copper buss, measures  very low Ohmage. Old age and
heat can develop cold solder joints. Worth looking and checking.

Tony, VE6CGX
P.S. I have a copy of service manual.
