Looking for some specific  20-50 Henry chokes for some passive low pass filter projects. I have three, but need to make some more filters.
These things were popular in the years of yore, as audio reactors, for parallel feed to tubes or transistors in amplifiers. Also used in 'wave filters'. These are the sizes that are less than an inch across. If you have any of these, PM me. Thank you!
