[ARC5] BC-348 Resistors

[Tim]

Hmmm  I have a BC-348R that has been playing fine for the 20+ years I have
used it and I have not replaced anything inside.  A Swap Meet Special that
appears to be in Un-Hammered condition when I got it.   It has a
"commercial" ACPS installed.  I am either lucky (or more probably ignorant
of performance degradation...)
My Philosophy:  If it ain't broke, fix it until it is......

FWIW, Tim
