15B-6769 transformer from a Laser Ball game. Testing the transformer I found that the secondary windings for the soundboard has no voltage from gray to gray/green (gray/white common) on the lugs. Seeing that this hard to find at this time or crazy high prices, I found a mom and pop shop that can fix/rebuild the windings, but need to know the correct input and output voltages on the lugs.
Is there a place to find this information, as my search on interwebs has to produce any results.
Any help is much appreciated
