Connections and circuit (ideal SPICE model)
Inputs, outputs, power and control as its own documents name them (no RTO-144 sheet for it: pin numbers only where the page gives them). Run the generator, turn the gain, watch the VU.
Pinout & connections
Each contact as its own documents name it: 3 named (1 medium, 2 low confidence). An empty slot is a contact no page names. Hover a contact for its source; the table under the drawing lists them.
