Hi Sir Tony, I'm new in this thread, This is my first time to post a message here I always reading your thread in how to build/rewind a DIY Transformer I have learned more knowledge and I appreciate to this thread for your sharing of your experience and skills not only this thread also in other thread. You are really expert when it comes to transformer and analyzing amplifier designs.
By the way, I bought a step down transformer made from turkey which is the Primary voltage is 380-220-0 and secondary 0-12-24-48-110 rated at 500va 50hz, I know you can help me because i want to rewind this so that i can use it to my DIY amplifier.
Target primary voltage is 220 and my secondary is 50-0-50
My transformer size,
12cm lenght
10cm height
7cm width

Center Leg = 1 3\4 inches
Stack = 2 3\4 inches

This is my first time to rewind a big transformer, i have a photo of this transformer but i don't know how to upload it here.
Can you please give me the size of the magnet wire i could use in primary and
secondary and also for the no. of turns in primary and secondary.
Best Regards,
