Teletone verticle size

Ok well I have a 1k WW in there now so I'll leave it and assume it's right, I broke the old resistor in half and it's WW so maybe that's the right one. And I do agree that WW usually don't change but rather open.

Maybe the Sams doesn't show it as a wire wound, but the original Tele-tone print shows 1.2K WW resistor in the B-circuit.

With a WW resistor, often you can break it open and find a section that has continuity, and extrapolate the original value.
E.g., if half the winding is good and shows 500 ohms, the original will be 1000 ohms. Or if a third of the winding is good and shows 500 ohms, the original will be 1500 ohms. Etc.

Since WWs don't change value much, this method gives a pretty reliable approximation, considering standard +/- tolerances.
