Yes, the old ballast was rated at 277 volts/70 amps. I'll check them out if the place in Bellevue doesn't work out.

Try Platt Electric or Graybar. They're in the book. They may not sell them to you but they could point you towards somebody who would. You should check your ballast to make sure its rated at 120 volts. Some industrial florescent lights run on 277 volts. The "T-" numbers (T8, T12) refer to the tube diameter T8 is 1 inch. T12 is 1.5 inch.
