Ken -
The disc ceramic caps with paint on them are selected caps, typically
1-2%. I don't think I've ever seen one of those go bad. Are you
certain that is your problem??
The 2-B schematic doesn't have any component values for the PB tuner,
which is what all those caps are. The 2-A schematic has values, and I
have a schematic of the R-4B PB tuner on my CD. All the PB tuners are
the same, essentially, from the 2-A to the 4-B, just added selectivity
positions from 2 in the "A", 3 in the "B" and 4 in the "R-4/A/B"
Can you ID the capacitor you suspect on the 2-B schematic, even if you
can't read the value? My 2-A and 2-B schematics are clear, but there
are no values on the 2-B version. The 'purple' caps on the R-4B PB
tuner board are the coupling capacitors on either side of the center PB
tuner section.

I need some assistance in identifying a disc capacitor on my 2B.
Mounted on the passband selector switch, is a small disc capacitor,
connected to the two end connections on the terminal board. It has
some violet (paint) marking on it.
The schematic I have is very 'blurry' at the point I need to see.
I'll do a digital pix, if no-one can identify it.
thanks
