  • Need a formula from RDH3

    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.

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

        Thanks!
