First, keep in mind the set worked pretty good as is when I first got it.

After changing a 100k resistor that went up in value to about 1.4 meg on pin 5 of the vert osc, I got a double picture. I then tacked a 1.2 meg resistor in series with the 100k and the picture went back to normal.

Checking schematics, they do indeed call for a 100k resistor on pin 5. I then looked for other issues around the oscillator, but all seems well.

The vert hold control checks good within specs.

I checked voltages. If I leave the 1.2 meg resistor in there (that's not supposed to be there), voltages are off. Pin 5 should read about 65 volts... I get 12.5 volts. Pin 3 & 6 (cathodes) should read 2 volts... I get .4 volts. Even though these numbers are wrong, the picture is fine.

When I remove the 1.2 meg resistor and only use the 100k as I should, all voltages become exact to what the paper work says... but yet I get the double picture.

So... question is... should I leave the wrong resistor in there since it produces a perfect picture? If no, then what else should I look for?

While I realize schematics can contain errors, remember that this started because I replaced a 100k resistor that was reading 1.4 megs. In addition, you'd have to be legally blind to mix-up brown-black-green and brown-black-yellow.

Thoughts?
