[Boatanchors] Old resistor values

[WA5CAB at cs.com]

Mark,

The difference in OD is apparent but not that great.  Plus most of the newer 
ones are dumbbell shaped.  The ends are almost as large as the equivalent 
carbon comps.  And unlike capacitors, resistors needing replacement are often 
crispy critters.  So there is no shell to salvage even if you have the equipment 
(minimum of a good lathe) with which to do it.

This technique (drilling out the can) works with the earlier metal can axial 
lead capacitors if you use new ones with about the same voltage rating (they 
will be smaller OD), especially in sets like the BC-611 where the original 
metal can is in some cases soldered through the chassis.  The wire gauge of the 
newer components is unfortunately much smaller, however.  But you have to look 
rather closely to spot the repair.
