[sdiy] Ladder filter pole

[epeasant at telusplanet.net]

I was hoping that somebody would design one with tubes, but it might need more
than 300V. Diode tubes ought to work OK, though, and 6AL5's (dual diode) are
cheap and plentiful. If I ever get time I may take a stab at it; has anybody
ever attempted it with FETs?

Take care,
Doug
