I'd have to look at mine!
My set must be a TS4 series, as it was built in early 1949. Mine does have the Amperite glass ballast tube. If I needed to replace a defective ballast in that set, I definitely would go with capacitive reactance dropper scheme. There is a few WW resistors that have to be used as well.
