This chassis is strange. Yes, it obviously has some repairs done to it.
But many resistors, that seem factory, or at least totally time-appropriate, and do not seem replaced, are not in agreement with any values, even if corrected for time-related deterioration. And some are wrong with the markings, that do agree with their values.
Here.
This blue/yellow resistor (dogbone), which does not have the dot (none of these have dots. Some are painted with single color, grey or green), means that the value will start wth 64 (before the multiplier). The resistor shows 48K.
This is R14. It shows 13K on our schematic
https://philcoradio.com/library/index.ph...chematics/
And it says 13K on early and 33K on later models in Riders.
Let's proceed.
These 3 resistors on the capacitor block.
At this chassis photo (it is better than at the Nostalgia website, right from Riders) these aree R37, 36 and 35, respectively top-bottom-right.
The top is Brown and yellow. Which means it will start from 14. The sch shows 25K value.
The one under it is Green-black-red dot, which is 5.1K. And it does show 5.1K (wow, kept well over time). Except the R36 is .. 13K. On my schematic (which is posted above) this one is listed with R14, as 13K/33K early/later chassis.
And the last one, R35, is pained green (there are others painted like that), and they are all different values. NOt even close to 70K that is shown in the sch. Here's the photo of the others painted green.
I will proceed with the values shown in the schematic, but...it is puzzling; I never met time-appropriate factory-looking components that are so badly in disagreement with the documentation.
