Main Voice PCB Assembly
The Matriarch oscillators rely on a discrete exponential converter circuit to translate control voltage into frequency. Persistent drift after a 30-minute warm-up indicates a failure in the matched transistor pair or the temperature-compensating resistor responsible for stabilizing the circuit against ambient thermal fluctuations. Replacing the main voice board ensures that all voltage-controlled oscillators receive stable reference voltages and possess functional thermal tracking components.
