PLLXO with LR Filter

As Adason poimts out.mylink is for an RC PLLXO, but they can be LC. Inductor values are huge. Marchand makes the job easier by terminmating with a 5k R, so you need an amp with vey low Rin, and a preamp with very nhigh Rout. You need the same with a 2nd order RC PLLXO.

Yup. Show us some pictures, fr responses.

Long time ago i was interested in making active equalizer using inductors, but abandoned the project because of lack of high quality inductors. Then i purchased shiit eq, which does all that, so i replaced behringer ultracurve, used for measuring purposes only now.
