[sdiy] Discrete OTA

all this recent talk about 2164 Osamu's compensation made me finally go 
and seek for this circuit. What a surprise it was when I saw it's 
basically the circuit I originally posted here in 1999, only refined to 
find the magic number of 0.27V bias.

Well, the multimania site, where I used to show ideas like that, does 
not work anymore, and I didn't move all to synth.net when it started, so 
there's only email atached GIF that's out there. Another lesson that if 
something is not published in internet, it does not exist.

It's not rocket science and I'm not claiming any rights to this very 
simple circuit that is so obvious to come up with. But still kinda feels 
like Antonio Meucci...

or maybe I'm just having a bad day today...
