One particular "gotcha" as per A.B. Bonds is possible carbonization of
the bandswitch wafers which can eventually cause arcing and damage to
components, like coils, etc.  This comes about, as I recall, from bad
caps and/or dirt buildup.  Actually, it's a chicken and egg problem.  To
head it off, clean the phenolic wafers with alcohol.  He found some deep
carbonization which he managed to clean out.  I think the theory was that
bad caps caused the arcing, which cause the carbonization, which in turn
caused a downright short.

As you probably already know, be careful with DeOxit on the switch wafers
-- don't spray them -- just apply to the rotor traces and work the switch
in.  If DeOxit soaks into the phenolic it may swell and cause binding.

There's lots more of value -- found the URL --

Anyone heard from Mr. Bonds lately?
