[ARC5] Carbon Comp Drift

[Glen Zook]

I haven't used a carbon composition resistor for much of anything for quite some time.  There are still a relatively few of those resistors in my parts drawers, but, for the most part, they are just occupying space!  There are a few applications where carbon composition resistors may work better.  But, those applications are getting fewer and fewer.

    Heat always seems to make CC resistors go high. Evidently 
that is why they are never closer than 5% tolerance, the heat of 
soldering them in can make them move more than that. Metal oxide 
resistors are probably the best replacement for composition 
resistors in applications like cathode resistors. Not expensive.
