The Wentworth, eh? Nice.

It got dark fast. I cleaned up some of the tubes, and cleaned the HV cage and tubes. Several shields are missing.

Found a replaced tube: A 6AQ5 vertical output... 70's RCA replacement.

The HV tubes are all original.

Pulled the horizontal output tube.
Brought it up on the variac over an hour. Nothing bad happened. Inserted the horizontal output, and it red plated as soon as it started to conduct.

Looked some more, and found the horizontal oscillator was not running. 6CG7. Pulled it, cleaned it up, and its socket, and now we have raster, sound and some deflection. Turn up the color intensity and we have major red smearyness.

I've checked all the sweep tubes, and all test good. Move the tuner, and get some noise. Tomorrow night, I'll run some cable out from the DVD player.

See the picture.

I'll have to wait to get the schematic from my sister to even begin with it.

I know it needs capacitors. The paper caps are gooey with wax.
