My Attempt at Predicta Restoration

[W9RAN]

Realizing this is an old thread, I'll just pile on to say that having just gone over a similar Predicta, I found exactly the same modification. The wire to the Vert Lin pot had been cut and an oversized 300 ohm 25 watt sand resistor hacked in it's place. Vertical linearity and height were horrible, but a few minutes with the sub box produced a much improved image with about 900 ohms. I assume this pot is prone to failure, and the 300 ohm value was deemed correct at some point.

That's a real nice power supply you've got there!

The Power supply shot is to Show The voltage and current of the "part" in the bowl was drawing and it's setting..(which was 6 volts).. interesting as soon as you lower the rusty metal part into the salt and water mixture it really draws some power during this process..... this why I am glad I don't have a Wife to get upset at me for using silverware from the kitchen drawer for this ...
