Need a formula from RDH3

[imaradiostar]

Hoping someone can help my remember a formula from the Radiotron Designer's Handbook. I'm at work and don't have a copy handy.

It relates impedance, low frequency extension and primary inductance as a formula. Anyone have any idea?

thanks!

Maybe I meant RDH4. My bad.

I think this is what you are looking for, it's on p.212 ...

Yeah, that's pretty much it. I have to apply it to a modern solid-state situation.

Thanks!
