Re: Happy Fun Band...

Disclaimer: Don't anyone go out and do anything suggested below:

The way I do tube repair is this.

1. first put on all the safety equipment - face masks, gloves, etc..., then
carefully puncture the little tip at the end of the tube, but with some
vacuum gum on the puncture area.
2. through a small capillary tube, allow the vacuum to fill with air.
3. Next, safely remove the band and replace the ears, and make sure the
strap is tight.
4. When that's done, pull vacuum on the tube with a good vacuum pump (which
can be made from and old refrigerator compressor.)
5.With that done, carefully remove the capillary tube, but leaving the gum
to seal the opening.
6.Now, power it up and it should work fine now, but with the corrected
mounting tabs.

If the picture becomes a little dim or blurred over time, go back to step 4

Note that while the tube vacuum is released, you can do all kinds of neat
things. My favorite is this:
If the tube has bad gun(s), carefully scribe the perimeter near the end of
the neck then tap the end to release the guns and socket.
Now you can remove the electron guns and play with them and either fix them
or change them out with a working set from another monitor.
When replacing them be sure to pay close attention to alignment as it is
critical. Seal the cut with vacuum gum and a strip of duct tape. and pump it
down.

If you feel daring, you can also scribe the edge of the tube so you can fix
or replace the shadow mask.
