What I have been asking Santa aka Farhan is for a similar circuit that just plugs in to the existing 8 pins.
No need for output caps and such as it is already there!

Ash and all,
Jerry Gaffke provided a valuable link:
the second circuit (without crossover distortion compensation) seems to me to be more than adequate, with extremely low? THD.
Uses fairly common parts, and not very complex.

John, others,
Given our experience of the non-generic ICs going out of production, it is best to stick to either discrete or generic ICs. The bitx20 will soon be a 15 year old design. The NorCal is probably older and still being built. We will have to choose parts that are going to be around for a long time, that are easily substituted. This means, we must work with large design margins, discrete or generic ICs.
Given these limitations, we are pretty much limited to either op-amps or discrete devices.
Opinions?
