| Notes | The Moog 921 is complete oscillator with additional Aux Outputs and a Clamp function. The Range has one more setting of 1' and the Lo function has been moved to a toggle switch. The 921B Oscillator is a 2 MU wide module with PCBs on both sides. The right PCB appears to be a depopulated 921B PCB. Four of the trimmers for scaling on this module are multi-turn. |
