Bob, Thanks for taking the time to reply. It's appreciated.

#1 is listed as C403 .0047mfd mica or 4700pf
#2 is listed as C404 .006mfd mica or 6000pf
#3 is listed as C413 82mmfd mica or 82pf
#4 is listed as C420 470mmfd 5% mica or 470pf
#5 is listed as C421 .001mfd 5% mica or 1000pf

Both Sams and Rider's agree on the values. As you can see #1 and #2 differ. #3-5 agree with both parts lists. BTW the part designators are from Rider's.

I then remembered that my multimeter can check the values of capacitors. Both #1 and #2 measured out to 4.70nf or 4700pf.

I really don't know why the color code is so difficult to determine the value of these caps.

Looks like I'll be using 4700pf 5% 500V Silver Micas for their replacement.

I'm including the schematic from Rider's.
