Circuit diagram notes :

1. All resistance values are in ohms, K=1,000, M=1,000,000.

2. All resistance rated wattages are 1/6W unless otherwise

3. Excepting electrolytic capacitors, all capacitance values of

less than 1 are expressed in µF and more than 1 are pF.

4. All capacitance rated voltages are 50V unless otherwise

5. All inductance values are in µH.

6. Voltage readings taken a digital voltmeter are from point indi-

cated chassis ground. Voltage readings taken by using a

colour bar signal are with all controls at normal position.

Some voltages may vary with signal strength.

7. Waveforms were taken with colour bar and controls adjusted

for normal picture. Waveforms were taken by using a wide

band oscilloscope and a low capacity probe.
