Based on your knowledge is this correct? Thanks for you help.

I have a Motorola 9VT1 electrostatic set that I restored years ago. The ballast tube just went one day when I was watching the set. It was as though someone pulled the plug. I like the idea of individual resistors as replacements and I think that is how I will go with mine.

I have the Sams Photofact for the TS18 chassis. If you want it, I will scan it and e-mail it to you free. Since Adam was kind enough to give me a knob for my Zenith color roundie, I want to return the favor by helping someone else.
