[Amps] Use of toroids in tank circuit of tube amp?

[Radio WC6W]

Hi David,
  If you follow this link to the archives you'll find a lot of info on the topic in general:

  And this one in particular:

  Though, the short answer is that at the impedance levels typically employed with a 4-1000A, toroids are impractical approach.

73 & Good afternoon,
