PS: Pay attention to do something similar because you can damage your game...
Probably a lot of you already know that but I want to add this post in order to avoid shocks or other problems.
Primary coil is the part of transformer connected to the power line.
Secondary coil (typically more than one in the same tab) is electrified by electromagnetic induction by the primary coil. no contacts between primary and secondary coils, but they have to be aligned.
I don't want to explain the theory of operation of linear transformers but I just want to say that in order to have a specific voltage on the secondary coil you have to calculate the ratio between turns.
the formula is:
Primary coil voltage : Primary coil turns = Secondary coil voltage : Secondary coil turns
so if you have 220VAC and 300 turns on the primary coil and you want 6.3VAC on the secondary coil you need
(300 x 6.3 ) / 220 = 8.6 (rounded to 9) turns.
So the number of turns is very important. If you want to do something similar to what I did you have to know how many turns your coils have.
