Install Col-R-Tel TV Converter, Part 4

    • NOTICE: In the next few steps, you connect the vertical output tube plate to your Col-R-Tel converter. If you can easily remove the chassis, solder the blue lead (Item D) to the socket plate connection. If chassis removal is difficult, follow the instructions below.

  1. The kit provides four spring clips (Item I) of different sizes. Find the clip which best fits the vertical output tube's plate pin.

  2. Connect the blue lead of the cable (Item D) to the clip (Item I).

  3. Insert the tube into the clip and then the tube socket.

  4. Dress leads to prevent shorts.

  5. Connect the black lead of the cable (Item D) to circuit ground (usually chassis).

Install Size-Control Box

  1. From the kit, get the picture size control box (Item C). Note the four leads coming out of the size control box: Red, black, green and yellow leads. You'll connect these leads to the deflection yoke.

  2. Connect the red lead to the deflection coil's high-potential side.

  3. Connect the black lead to the deflection coil's low-potential end.

  4. Connect the green and yellow leads across the vertical deflection coil. On the vertical coil, polarity isn't important.

  5. Dress leads for proper connection to the converter.

  6. Install the back on the television receiver.

Finish Assembling Electronics

  1. With the provided screws, mount the converter and size control boxes.

  2. Connect the picture tube yellow lead (Item H) to the converter yellow lead.

  3. Cable 
           connections between adapter box & picture tube (mechanisches Farbfernsehen). Connect yellow and green wires
  4. Connect the picture tube green lead (Item H) to the converter green lead.

  5. Plug converter cable connector P2 into TV set connector P1 (Item D). (This cable carries vertical and horizontal signals from the TV to the converter.)

  6. Cable 
           connections for vertical & horizontal signals: Col-R-Tel connectors P1 & P2 (mechanisches 
           Farbfernsehen) Connect P2 to P1
