8038 circuits were much recommended, but I suspect too often by people that had never used them. Wanting a cheap sig gen once I built one, and found t he descriptions square, triangle and sine were decidedly optimistic. To get one working passably required a scope to set the waveform shape by eye, an d of course it needed a retweak at every frequency change.

We ended up using the xr205 instead. As in
At OmniComp/GenRad I used an AD630 and an AD639...
with embellishments to control accuracy and distortion. ...Jim Thompson
I used to like the AD639, because if you drove it with a sawtooth instead of a triangle, you could make a nice phase vernier by just changing the DC offset.

Yep. It was a major workhouse for the times. ...Jim Thompson
