Just to add further facts and cause confusion, I found a box of new (i.e.
unused) 150Kohm, 1/4 watt, 5% carbon comps last night, said box being dated
1974. I measured 10 resistors, and the worst one measured 151.5K ohm. That's
getting to within the accuracy limits of the DVM......
A used 47k carbon film from the 1960's measured 47.5K, while a 50K, 10% of 1935,
out of my old HRO, measured 55.6K.
Makes me wonder if resistors have got worse
