I just built a transformer to the specs of the original. The transformer has a turns ratio of 1:16. Input to primary is 12V. The problem I am having is a very low voltage at the secondary side. The no load voltage was the highest (40V) that I have got out of it so far. The primary coil has a 200 Ohm resistor in series. I removed that to get more current to the primary but got the same results? Anyone here have any suggestions as to why I'm not getting the full secondary voltage?
