Favorite designs

[Paul Schreiber]

Slow down Bjorn.

All I'm saying is that

1) nobody says you have to use CA3080s, just because "everyone else is". This is the main point I'm trying to make. Most synth designs are NOT taking advantage of the technology.

2) No, I'm not a God. Or bad-ass. Actually, I'm a middle-aged balding guy with 2 kids.

All of the really cool parts are duals, and quads crosstalk too much (If you really need a quad, use the AD713KN. Awesome!) For duals, look at OP275 or LT1113CS8. Stay away from junk like 1458s. Think of a TL072 as the BOTTOM rung of the food chain.

Man stop stop plase bee halted, You are long away in the spaceright now
I have designed an entire system with among many the LM13600 and i think
you are on some thing alkoholic
rhigt now.

If you where right on the CA3080/LM13600 issue why would so many
manufacturers have build systems on them?
And there are still manufactures today who build on CA3080.

And finaly what do you mean with "  im a  former Moog designer for 20
years. Bad or God? :)
