[OldRestorer]

Ok I am getting back into these chassis and am lost with these resistors.

Reading resistors:
You can see the 3 resistors in the picture above. I know 2 are 490'000.00 and the other is 240'000.00 by looking at the schematic but how do you tell on the resistor? The 490K body is yellow and the end is white but no dot? Same for the 240K. red body, yellow end but no dot? Is there a different way to read them?

Next is this:

I measured the 51'000.00 51K and got 58.8. Is that too far off? What is the percentage again? I looked online and see a lot of 20% so I just want to make sure.

I remember someone saying to remove one end before checking resistors. Then someone told me it was a waste of time.
what do you guys think?

Also I measured a 10'000 watt resistor but it is coming up 9'500. One or 2 others are also coming up lower. Is that normal? Does the 20% work both ways?

Lastly, I purchased all the resistors of common values but none of these really are the same. I have 10K but no 49K. All I have is 47K.

I need an exact duplicate right?

Sorry for so many questions but Resistors are something I barely learned and then I stopped doing chassis for the last few months since Mike was doing them for me.

Thanks for any guidance
