[ Follow Ups ] [ Post Followup ] [ Thread: Display Email Next ] [ K&K Audio / Lundahl Transformers ] [ FAQ ]

of 60 to 90mA? What's SE output tranny do you have for 300B? Iplan to use this plate choke for SE 300B also. Thanks

The highest current audio choke in the line is the LL1668/60mA. It might be possible to get a bit higher current rating, but I would have to consult the factory to find out.
If you want secondary impedance flexibility (4/8/16 ohm), the LL1623/90mA is the choice. Otherwise you can save about $60 by choosing the LL1664/100mA and accepting the fixed 3K/8 ohm ratio.

  What is the inductance rating for the 1668/60? I looked on your website, as well as the Lundahl site, and didn't find it. Same price as the 1668/25, or more expensive?
  Thanks!

    It is about 35-40H with the two coils in series and it is the same price, but I don't stock them. I can easily order some, though.

      Note that the 1668 is also available gapped for 40mA. I use it for a plate load for 6C45P - my "Free Lunch" amp's driver. Works like a charm.
