I have been winding some transformers recently and have been getting some odd results. All cores have a prim of 9 turns and 27 turns sec. 1. 3C85 58 mm diam Prim inductance 167uh Sec 744 uh 2. Same m
Mal reflected resistance of a typical xfmr used in LF setups... Imagine the two impedances in // as the inductive reactance increases on the smallest winding it has less and less of an effect on the
Hi All Another anomaly about these ferrite transformers. I wound a 3c type core with a Sec of 24 turns and measured it to be 1.38 mh then over wound this with the prim of 8 turns, this reduced the Se
The old 3c5 tv line o/p transformers are equally as good as the modern 3c8/3c9 series. I have subsituted these for the 3c8 type and the output is exactly the same and they do not get hot up to the 1k
