[sdiy] Discrete Op Amps

[cheater00 cheater00]

Wow this thread really deteriorated quickly. Can we get it back on track
please with arguments that can be backed in a technical manner.

Tom would you mind posting what you think are a few (guessing ~10?) main
types of differently behaving op amps to check out?

Everyone: do you think the assertion is true that a discrete op amp can be
made cheaply with SMD? Do you think it's a good idea to use that as a way
of tuning an op amp to your circuit? Do you have characteristics you desire
most? For me, one application could probably be for late gain stages: high
headroom and running off relatively large voltage rails, high current
capability, soft clipping, and low bandwidth not far beyond 20 kHz in the
gain i use it in. Some circuits might better like 2nd and 4th harmonic
clipping, others odd harmonic. Has anyone here tried their hand at building
a simple discrete op amp?
