Predicta Holiday restoration

[StellarTV]

Now that you've put the RTV on the flyback this may be a moot point for this particular discussion, but what does the jury say about using the High Voltage Corona Dope that comes in the jar with the little brush? I've never tried it to completely recover a flyback, but it works great for insulating other sensitive points in the HV cage. Why not recoat a fly with that?

[bandersen]

I've used dope to touch up a few hotspots on flybacks with good results. It might not work so well on the whole donut and over the remains of the old coating though. The RTV is very tough and flexible while the dope it hard and brittle.

Figures with that concentric shaft setup. Mine aren't the exact same as the the ones I linked to earlier. Mine are possibly a 20 year old OEM part with a plastic shaft. Anyhoo...

Did anyone ever use that tool handle insulating dip for covering a flyback or other parts? Should be able to brush it on.

[Kevin Kuehn]

Not sure if it would have the required dielectric properties.

[Reece]

Rather than tool dip, liquid tape might do it. Available in spray or brush on. They say:

"Liquid Tape has the strongest dielectric protection on the market; 1,200 v/mil, 5 – 7 mils per coat."

They recommend applying several coats.

Bob, did you see this on the Early TV website?

I have a number of the Push-Push Off-On switches for Predicta televisions. These are new old stock and are $19.99 plus $5.20 Priority Mail. I take Pay Pal. Don, dpatterson002 at comcast dot net. (1/18/12)

Yes, that's where I got my switch

I've been working on the screen this weekend. There were some gouges in the plastic but wet sanding has mostly gotten them out.


A bit more buffing and I'll call it done.


The CRT sure was dirty

[DavidGoncalv]

Wow, is it supposed to be that yellow-green?

[bandersen]

Yes, it is. The later models like the Princess used a different kind of plastic that is clearer, harder and doesn't stink.

I KNOW that stink! I brought it all the way over to Australia!

A mixture of well worn athlete's runners, parmesan cheese, BO and goat vomit!
Fantastic job on the polishing, hope mine comes out like that when the time comes. Does the stink become less when you clean it? I've heard that it does. Looking at the cloth you used to clean the face of the tube, I wonder how many brighteners may have been fitted over the years that needn't have?

Looks great, curious what you used to wet sand it with? ie. grit and what you wet it with, just water? I have a GE portable with a plastic screen that has gouges I need to sand out too.

Yes, the stink is reduced with a good cleaning, but it's does creep back - especially on warm, humid days. Yes, it was quite dirty and I'm hoping it wil be noticeably brighter once back together.

Thanks. 320, 600, 1000, 1500 then Novus #3 and #2. Yes, I just used water.

Bob, I didn't realize that apparently the on-off switch on my new Philco set had at some point in the past been changed to a push-pull type, so I made the false assumption that your switch was the same type. The switch I posted the link to is a push-pull. Didn't realize yours had a push-push until I watched your last video.
