It ain't?  Correct me if I'm wrong, but 80Vp-p @ 50Ohms is 64W, is it not?
And you could eliminate the capacitor and add a pot to adjust the=20
offset.  But if the minimum frequency is 30Hz, why would it need to be=20
DC coupled?
It is unlikely that you will find EXACTLY what you want already designed=20
for you, but something close that can be easily adapted might be possible.
