[sdiy] sniffing

[harrybissell]

Hej Magnus

ain't that the truth... I've designed some circuits that have +/-100V swings on a
741
that way... as well as some that draw Kiloamps (worst case... of course)   :^P

I have never 'built' any of these so if anyone likes I can send them the schematic
to try
it. I'll even send you the first 741 to do it with (you buy the second one...)

H^) harry

BTW  I've liked some of the old Burr Brown four quadrant multipliers. (i forget
the number
this late at night) but they were lazer trimmed hybrids that cost a bundle...
sound good without
trimming as well...
