I’m not getting 12v to power the boards in a Bally Speakeasy.
On the rectifier board: At 11.9v test point I’m getting 6.0v DC. The rectifier board is brand new and that eliminated a bunch of other issues. But the 12v from the transformer seems to be the last problem. I never deal with transformers — is it time to pick up a used one? Or just throw a cheap switching supply in there?
I can actually run the new replacement MPU on the existing 6.5v and it works with all flashes, but the symptoms are that controlled lamps, motor, displays all don’t work. GI and coils do.
