L-49B Ballast tube. What are the resistor values inside?

Posted by Warren on 04/27/2010 17:18

The original ballest tube pins 3 and 8 for the main drop. pins 7 and 8 for the dial lamp shunt. What you have done from 3 and 7 with the capacitor, is by-passed the dial lamp shunt. That's why no light. If you were to do the dial lamp modification as I said, it would still work fine with an original ballast tube pluged in. IPAddress: ***.24.247.210
