[Heath] UPDATE Re: Heathkit HW-100/101 S-meter trouble

[Dick KF4NS]

Great idea Chuck. I planned on using my CW (Circuit Works) overcoat pen which can also be used to 
insulate any damaged solder mask but it is apparently as dried up as the three conductive pens. Tried 
dipping the ends in toluene but guess they have been on the shelf too long.

Thanks Chuck, et al for the kudos but I never want to go through anything like that again. In my younger 
days it would have taken me a couple hours to fix but age is taking it's toll.
