[sdiy] LM3900, was 566 , was Re: Midwest Analog Product Books

Oh yeah! It has been a long time since I've gone over the Gnome
schematic, I'd forgotten that it used LM3900s!

AN-72 is great. These amps can be applied in so many applications,
though I can understand if some might note that they are not the best
possible chip for each of these. I was trying to find my few LM3900s
this month, missing, booty I am definately going to get some more of
them.
