The other resistor appears to be a 22 ohm resistor reading 208 ohms, which is leaving me  , but in any event both have obviously been overheated and aren't what they should be. I bet these are what got toasted when the yoke failed.
I ordered 5 watt replacements from Mouser, which are en route. Hopefully this is on track to curing the wild linearity issue. |
Those are the B+ resistors for the vertical stages. They get burned up when the vertical section develops an overload. They definitely need to be replaced.
