Wanted to share this.

another flowchart. Plus I wanted to start a discussion on the motown eq.
from what was said by John windt. The eq was passive and used similar tech as the langevin graphic eq. Faders were replaced with stepped attenuators and the eq consisted of 2 smaller eq’s wired in series. This allowed for the bands to not overlap. You will note there was a Fairchild line amp used for insertion loss however when it was decided that the tech department would build 40 of them for Motown, the Fairchild line amp was replaced with an opamp labs line amp plugin module. The transformers were custom made for Motown.
