Hi All,


Any obvious reason that this isn't a common approach ?

Ian ? Anyone ??

Thanks,

Yep - push pull amps make wonderful frequency multipliers. In the days
when there was nothing in use above them, it didnt matter. Now it does.

All class C amps make pretty good frequency multipliers. If you're
worried about the -second- harmonic, then p-p is superior.
