I finally got one!!! Philco Predicta

Replaced C1 C2 and C3 this restored brightness but did not solve the deflection issue. I will figure that out next.

I fixed the power switch, inside is a little brass piece that gets turned when you press the putton, it has 2 little "tabs" that stick up and grab the part that turns. On mine the 2 little tabs were bent down and we just about flat. I pushed them back up (And ran the little screwdriver into my thumb). The little thing that turns now makes contact and the power switch works!

I did make a mistake when changing C2, I had 2 of the wires wrong, one is blue and one is green and I had them connected to the wrong place. Got some smoke from a resistor when I was bringing up the power and stopped to find the mistake. That blue wire is ground and the green is not. Did not seem to cause any damage.

The picture is with the lights on in the garage, it was too dim to see the screen with the lights on before.
