Hi Nino
re; change my mm from ac to dc, I don't think mine has either(or both), it just has one range from 200m to 600v, guess it just knows whether you are checking AC or DC and gives you a reading regardless.
I definitely have no voltage at TP4 so something is up, however the cabinet lights are working so not sure whats up there.
In your post on rebuilding this board you mention you wash everything in hot water and nifti, do you mean the transformer as well??,
When you say you fit the bridge rectifiers and fit the heat sinks later, where are the heat sinks fitted, do they go under the bridge and between the board or do they sit on top of the bridge??
I tried to follow the link to
http://www.pinrepair.com/bally/index1.htm#ps but it is a broken link.
Still trying to work out a parts list, I see Jaycar has the 35a bridge rectifiers but their fuse clips look a bit budget, especially after reading your preferences for the low and high voltage fuses. I know I need resistors and diodes but I'm not sure what the values or part numbers are.
