Any quick fixes before I go back to staring at it?

There’s about 2 million posts in this forum telling you how to measure the inputs to the CV summing node (pin 15) . Here’s one:

Also some trouble-shooting tips, from here: Turn the coarse tune knob. If it doesn’t change anything, check the wiring. Measure the voltages going into the CV adder, via the 100k resistors at the top, marked with “CV” and “TUNE CV” here: Annotated Simple 1V/Oct Oscillator Stripboard Measure between ground and the top of the resistors, away from pin 15, and add the voltages. You need almost 5 V in total to reach audible frequencies, and about 9 V to hit A4 at 440 Hz. Check the oscilla…
