I have a schematic for a heated differential pair based on the
AN299 National Semi schematic... that would work. I have a PCB
layout also. I doubt it will work quite as well as the uA726
because the diff-pair is not as good, and it will take more
power to heat it.

e-mail and I'll send to who wants...
