Wondering if I can use a Williams Stellar wars Transformer part# 15B-6796 in a Bally 8 ball?
I wasnt sure if maybe I could pull the correct voltages from this spare transformer that I have.
The 8 ball Transformer is not getting HV at the appropriate lugs. Someone has obviously attempted repair previously but its still not working properly. I assume a broken winding.
You’d need to look at the output voltages. I think Williams transformers ran different voltages for input to the solenoids.
Another option would be to eliminate the need for a hv circuit and change to led displays.
Possibly. What are the ratings of the xfrmr to be swapped? Will the ratings of the replacement xfrmr might the needs? If so, then yes.
Assuming both xfrmrs output the same secondary voltage (primary will be the same) you just have to make sure the replacement xfrmr is the same as, or has a greater VA rating. You can't replace a 100VA xrfmr with a 50VA xfrmr, but you can replace a 100VA with 200VA xfrmr for example (with the same primary/secondary voltages).
Fun thing about pinball. If you ask, someone usually has what you need and will usually help you out. Put the right parts back in it and make your life 1000 times easier. Yes it can be done but it’s more work and more time then you want to spend
Quoted from jgreene:Another option would be to eliminate the need for a hv circuit and change to led displays.
Wouldn't mind considering that option if I didn't already have a full set of plasma ready to drop in.
I seen another thread where vid1900 was talking about local transformer repair? Is that even a thing anymore? I've never even considered the idea.

You need to be very careful with transformers because voltage and amperage are two different things. If you have ever wondered why say Gottlieb had 20 different transformers in different EM machines - it wasn't because they were just screwing with you. Each transformer might look the same but the amperage output for each voltage varies.
If you are not getting enough amperage output you will be overheating the transformer and also a machine will not play like it should. So always replace transformers with the exact transformer that is suppose to be in a machine NOT just something close to being correct.
