half section of a custom double c core output transformer on DIY winder,
Believe me this is hard work
Wow... you wind your own trannies? How long does something like that take?
Pretty cool. I bet you have a lot of friends!
You cant ask friends to wind for you or with you, unfortunately no way to wind up with friends with this hoby!
Transformer winding requires a lot of physical labor. With a primitve winding tool like I have got, it takes about 20 to 30 hours work each. The bobin end is also custom designed PCB enables soldering coil ends directly. The coil is 14 layer interleaved with very good primary to leakage inductance ratios.
