Name

Function

1

GREEN

FEEDBACK

Feedback Output for ’Green’ Amplifier. The optimal value for the resistor connected here to set

gain is 68k

Ω as shown in fig. 1.2. Other feedback connections are pin 2 (red) and pin 14 (blue).

2

RED FEEDBACK

Feedback Output for ’Red’ Amplifier. See pin 1.

3

RED OUTPUT

Output of ’Red’ Video Amplifier. See pin 15.

High Voltage Supply for Amplifier Stages, Typically 200V (see fig. 1.2).

5

FIRST GRID

VOLTAGE

6

RED INPUT

Input of ’Red’ Video Amplifier. See pin 7.

7

GREEN INPUT

inputs are pin 6 (red) and pin 9 (blue).

8

GROUND

Ground Connection (pin 8 is also connected to the tab).

9

BLUE INPUT

Input of ’Blue’ Video Amplifier. See pin 7.

10

The reference voltage for the three amplifiers is available on this pin. Typical value is 1.6V. The

capacitor connected between pin 10 and ground eliminates AC crosstalk between the amplifiers.

11

Supply Voltage Input for Low Voltage Circuitry, typically 12V.

12

SAMPLING

Cathode Current Sampling Output. Provides sum of cathode currents for automatic cut-off

adjustment with in flowing CRT leakages.

13

BLUE OUTPUT

Output of ’Blue’ Video Amplifier. See pin 15.

14 BLUE FEEDBACK Feedback Output for ’Blue’ Amplifier. See pin 1.

15

GREEN OUTPUT

Output of the ’Green’ Video Amplifier. The output is protected against CRT flashovers. Other

outputs are pin 3 (red) and pin 13 (blue).

TDA8153

2/11
