NOTES:
1. Resistor values are in ohms (k=kilo-ohms, M=megohms).
2. Capacitor values are in microfarads (p=picofarads).
3. £Parts marked with this sign are safety critical components.
They must always be replaced with identical components-refer
to the appropriate parts list and ensure exact replacement.
