[AMRadio] Can you have Class D and Class E tube amps?

[Chris Wilson]

27 December 2016


I am a UK ham experimenting in a costly way with FET based PA Class D
and Class E amplifiers on LF (136kHz). My naive question is can a tube
based amp run Class D or E, or are the modes limited to
semiconductor amplifiers at these or any other frequencies? Thanks,
slightly off topic I know, but I believe you AM aficionados know about
this sort of thing? Thanks and a happy Christmas and a healthy and
prosperous new year to all. 2E0ILY
