[AMPS] G2DAF circuit and pictures

[Phil Clements]

It would be nice if someone would put up a schematic of a DAF
amplifier so those of us who have no earthly clue of what you guys
have been talking about for lo these many weeks can see it.

>From what I have read so far here on the reflector about the DAF,
I think Al Gore would call it a "risky amp scheme."
