Hi Ai2,
The dogbones are dfferent than the three color bod end dot marking. These are either one solid color, I think the orange was 50,000 Ohms, there were others that had only one color and you have to use the legend on the diagram to tell what was what.
I have found lower BED resistors to be out of whack also in addition to the higher values. Some do hold their values,(for some reason) so I leave them alone. It does make sense to check all of them.
The volume control issue, many can be cleaned, but often the carbon may be worn thru. Less sommon are the wirewound elements being worn, but I guess it happens.
On volume controls where a substitute is hard to fins, some have used 'resistance' paint, such as that used to repair the rear window defogger. They have had mixed results, so it may be worth a try to save an original control, until one is found.
Take care,
Gary.
