Pix Tube Replaced

[jpdylon]

Are the pix tube numbers the same? Sometimes a replacement tube doesn't have exactly the same pin layout as the old tube. Occasionally the screen or grid pins may be moved one over. I would see if the tube came with a pin diagram, or look it up online if you can. Compare it with the pin layout on the socket. If the old tube worked it may just be pin relocation.Ther also can be instructions for adding a jumper on the tube to comply with the way the old tube was used. Were there any jumpers on the back of the crt that you may have missed. Also don't neglect old connectors on the crt socket. I would crimp them a little to ensure a good connection.

Sorry if these sound like an insult. I'm not trying to challenge your experience in any why, just trying to think of all the possibilities.

Does the tube use an Ion trap?
If so it could be misadjusted, on the other hand if your old tube used a trap and your new one isn't supposed to that would cause a problem too.
What is the tube number?

The trap is a small magnet mounted on the neck of the tube near the base cap.
