I had a light ballast fail on my Tron. The one right in front of the control panel pulled it all out and checked everything. Bulb good started good 116v present. Metered the transformer open. 0 ohms. Swapped in another one I had from a different fixture. And we're back in business. Worked for about 2 hours. Now that light is dead and the light below it (the one above the coin door). Each fixture has a line filter on it, can these line filters fail and cause the transformer to go out? 3 transformer failures in a matter of 1 day seems odd to me. Granted these are all at least 40 years old now so could just be their time. I ordered 2 brand new ones and would like to see if I need to look deeper before swapping them out.

This machine has been in the same place running on the same power for the past year so I don't think it's a dirty power/ home wiring issue.
