Besides efficiency this is true, but with G2DAF its a freebee....

God point Lars, however don't you have fast VOX tr/rx switching  in your =

G2DAF amp  regardless it's a frebee or not, The need for fast switching =
are also for other reasons, and those reason gives a cool/slowblow AB1 =
amp as a freebee.
