Hey Chuck,4. Inserted 10K resistors (R103-R106) in series with pins 1 & 16 on IC1 & IC2. Pins 1 & 16 program the operating current and gain of each amplifier. The way EQD connected them all in parallel, there is no guarantee that they will share current equally. Putting those resistors in forces them to share. Should make for smoother phase sweep. Optional, but highly recommended.
I have a question regarding mod #4.
So am I supposed to clip the 1 & 16 leg on the IC1 and IC2 and solder on a 10k resistor like the paint image below?
