Bob,
I usually hang out in the vintage color section, but while perusing the B&W came across your Predicta restoration site. I was hooked and read it start to finish. Great photos and step by step progress reports. Looking forward to seeing the finished set with your choice of cabinet restoration. Thanks for sharing, -Steve D.

You're welcome. It's taken some twists and turns I didn't expect. As for the cabinet, I'm on the fence about using veneer or Di-NOC.

Here's a shot with the safety plastic removed. That's quite a difference! It reminds me of the Hoffman "Easy Vision" safety glass.

I wonder if they were that green when new or if time has taken a toll?
Also the 17" sets have a clear screen so that would indicate they didn't intend for the 21" models to be green but the type of plastic may deteriorate with time. It has to be harder on the CRT as well having to be cranked up to compensate for the darkness of the cover. The Hoffman is a little greener but also a lot clearer because it's actual glass and not 50 year old plastic, though there is a lamination layer.

Your cover is much greener than the one on my 21" barberpole. It sits about three feet away from my 17" Siesta and I just turned them both on for a comparison.
Now that I'm looking for it, I guess the 21" screen appears very slightly green next to the 17" set, but I have played the TVs together many times and that never occurred to me. That cover has also been less stinky than what some people report. Until I read about it in forums, I hadn't noticed any smell at all. Perhaps the two are related (more stink = darker green).

This comment not related to tint but directed toward focus of the picture:
Both the 21" and the 17" models have a focus "jumper". Usually one position is superior to the other, so try it in both.

I received a sample of Mahogany Di-Noc today. I think it looks great and plan on using it. it sure will save time versus using real veneer and having to glue, fill stain and finish it.
It's not quite the same color as the old finish though. So I'm pondering if I can get away with just coating the damaged center section or should I redo all the photo finish areas

From the picture it looks enough different in color that you'd probably wish you had done the whole set, if you only did the middle.

Yeah, I agree. I'm currently leaning towards trying to replicate the photo finish using these techniques. It won't cost much to give it a shot.
Meanwhile, I've moved on to cleaning the CRT housing.  Years of cigarette nicotine attracted by the HV I bet  It cleaned out easily with some "Spray Nine" my new favorite multi-purpose cleaner. The CRT inside is a genuine Philco replacement 21FDP4.

Most of my sets have that nicotine film on them when I get them. I suppose we are all used to it. I am amazed when one doesnt have it. My Predicta and my Admiral had none. And both are in super nice shape. I really think they spent their lives in one house and obviously no smokers. I sure have enjoyed this thread.

You may want to look up "retrobrite" online.
From what I can see, this stuff is ideal for our vintage projects. You can't buy it, you simply make it yourself. There are recipes and it looks pretty easy. In the instance of the CRT case on a Predicta, I'd try some on the inside first in case it takes the colour back too far. It consists of hydrogen peroxide and a few other things. When time permits, I want to try it out and I think it'll remove that faded yellow/brown colour. I'd love to hear if anyone has already tried this!

It's really not necessary on this set. The color of the case is correct and the gunk on the inside cleaned right off.
I have read about using similar products on vintage computers and gaming consoles with mixed results.

That brown color is correct for the Predicta, the discoloration on newer stuff is caused by the Fire Retardant additives according to what I read, probably not an issue in 1959.
I see a lot of newer Plastic sets that have discolored though, especially if they are White or Pink to start with.

 I regularly look for Tandems on ePay, and it's interesting to note that the CRT case seems to show in a range of shades on the various Predictas that show up. I can't tell if it's the white balance setting on the camera, or if the plastic goes darker over time. I too have read about the flame retarding chemicals in plastic going browny yellow. Does anyone know if the green area at the front edge of the screen should be tan in colour? Mine is green and it looks OK. Catchya, Adam
