I stumbled across a sealed transformer (step-up) which i believe came out of a neon power supply. Its completely covered in epoxy like goop and the internals cannot be seen. However,on the tin it indicates a output voltage of 10kv but i have huge doubts if it takes 230V in the primary.
I have taken some readings of both the primary and the secondary using a LCR but not really sure if i can get a good voltage ratio.
I'm just willing to know what's the best way to drive this.. (P.S no feedback coil either) The right hand side was the input for 230vac. Left side is the output. And the soldered points is the primary winding. I have NO idea what happens in the right side all is assumed. I also do not have a lot knowledge in transformers. (learnt physics up until 12th grade) Thanks,
