All TS-4 versions prior to TS-4J use the 17A470303 ballast. It has an extra resistor only used in the very early revisions (prior to the TS-4H).
The other difference the is that the AC line in goes to pin 5.
It is connected to pin 6 in the later version of the ballast which is what you created.
So, you need to move the wore from pin 5 to pin 6 on the ballast tube socket. OR modify the ballast so the CL-90 goes to pin 5 instead of 6.
