uA726 replacement, (the comedy of errors)

I thought that was a great post Grant, thanks for sharing your experience!

This line at the end caught my eye:

I am experimenting with an integrator/comparator saw VCO ("ASM1 style")
that does this.  Unfortunately it also has an additional "wobble" of about
+/- 5 cents with a period of about 15 seconds.  I am stumped as to why this
is happening.  I've tried to use all the proper components: good power
supply, .01uf caps on the board from supplies to ground, MAT02 pair & C-2AQ
tempco heat-sink-gunked together, 50 ppm metal film resistors, multi-turn
trimmers.  Has anyone experienced this kind of behavior before?

Thanks,
