Cgs synth

The fault would be with a bad connection between the 4070 (pin 8) and the
4024 (pin 12). Possibly a missing link, or a bad joint or break in the
track. The counter is working fine if all other outputs are behaving.

other "2" divisions work fine.

the 4070, no change. continuity has been checked from the output at the
jack/led to the chips. the leds light/jacks work when plugged into other
outputs.

welcome the opportunity to learn from whatever mistake i might have made (or
from the remote chance that a part may be defective).
