Now that I've gained some experience from restoring a Holiday set, I've begun work in earnest on this set.
Here are some closeups of the old repairs.
I would have clipped out the old resistor.
The thermistor has been replaced. I'd better check it.
The schematic calls for a 30-6519-1 network, but I found a 30-6519-2. The difference being the value of resistance between points 2 and 6.
Maybe they ran out back at the factory and added the external resistor to compensate
