This is a guide to the tube removal and installation process for the Continental Electronics 816R transmitter models. It allows tube removal without moving the shorting plane!

SAFETY FIRST! PRIOR TO STARTING THIS PROCEDURE REMOVE ALL POWER TO THE TRANSMITTER AND USE GROUNDING STICK TO SHORT HIGH VOLTAGE BY SHORTING BOTH PLATE CAPACITOR TERMINALS TOGETHER.

1. Open cavity door and remove the front and rear parts of the fiberglass air guide held in place by nylon screws. Loosen upper and lower hose clamps on the plate blocker and slide blocker down over the tube as shown. (Note: Do not loosen center hose clamp, as this would allow blocker to come a part.)

2. Remove anode clip and lift tube out of socket using the handles on the top of the tube. The plate blocker will be removed along with the tube. There is ample space to pass by the air exhaust tube. Place the tube on a clean table and remove the plate blocker.

3. Install the plate blocker on the new tube. Carefully push the new tube with plate blocker into the socket being careful not to bend socket pins. Insure the tube is seated fully into socket. This is verified by observing that the tube screen ring is fully engaged by the socket or by using a light and viewing from bottom of socket to see that tube is seated on metal hex post inside of socket.

4. Install the anode clip, lift up the plate blocker, install the air guides and allow the plate blocker to rest on the top of the air guide. Position the hose clamps, top, center, and bottom, toward the front so they will not be near the tune or loading paddles and tighten.
