Another question about Zenith Disc caps.

[Eric H]

Got the linearity problem pretty much licked though it meant replacing an .033cap with an .047 to get the height control back to center instead of at one end.

The integrators were not bad, I replaced them with individual parts but it made no difference at all.

I don't know why I had to change the cap value to get it to work right, everything seems to check out OK but it just wouldn't work like I wanted it to.

Made a quick video of it running.
The background noise is a TV in another room.

This is using the like new CRT I was given, it doesn't use an Ion trap and was much easier to set up!
