Hey OM:

That's a nice link. But nowhere could I find a diode double, tripler,
or quadrupler detector.

Probably because they don't deliver any benefits?

Basically true but in 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.
