I see that for your 3 high pass RL circuits you have: Lundahl LL1531 Transformer. How did you connect this transformer so that it could be used as a 9.3H inductor? It appears to have 7 terminals 1H - what did you use for this?Sowter 9858 multi tapinductor I am building a PLLXO so I am looking for suitable high value inductors.Thanks, Shawn

I am sorry, It was 20 years ago. Lundahl had very good PDF files that described all mappings. If you look at the posts from this site I did described at that time everything I did.
