Good work. I was expecting 10 or 20khz bandwidth. What you show is beyond 100khz. I think I will make one.filament transformer ...…… they appear to be essentially identical
I want to not put capacitance on the secondary winding. (1:1 probe) So a 10:1 probe should be good.
I do work at 100khz to 300khz and would like good bandwidth and the 60hz cores might not do that but even 20khz bandwidth has many uses.
I will modify a transformer to get 100:1 or 10:1. My head hurts if I have to work out 17:1. lol
