Amperite ballast cross reference

Does anyone know the cross reference number for an amperite ballast for the Motorola vt71 tv, I know there are 2 different ones, ts18 and ts4d both are not interchangeable.

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.

17A485459 is used in the newer chassis - TS-4J and TS-18

17A470303 is the older one for the TS-4, TS-4B, TS-4C, etc...
