fairness to the folks who have never tried it you
MAY get some additional volume on a reasonably strong local station. You
shoot your selectivity and ultimate sensitivity in the foot, though,
because of the extra loading on the tank. ie, not a DX set.

There's one circuit floating around that uses a dual center-tapped tank
(so to speak) with a diode on each side and their outputs are combined.
One fellow said it worked pretty well as a workaround for the loading
concern. Still not a DXers set but better than attempting a voltage
doubling detector.

Basically a fullwave rectifier?

I'd still opt for a quality matching transformer, and go for the max.
volume if that is the goal.
