Zenith TV chassis 16K20 horn and fly
The horizontal linearity is not quite right , it pulls a little on the left side of the screen and crushes a little on the right , since there is no Lin where do I look or what would cause this ? It's not the sleeve on the neck of the CRT because all that will do it push the picture in on both side.
Next is the flyback , it does get hot and I'm wondering if there is a pin on the Horizontal Output tube that I should be checking the ma on like one does with a color roundie or porthole ? |

You check it at the cathode of the hoz output.
Break the connection, put mA meter in series. You also need a cap across the meter IIRC a .01 but check the manual. Also check the G-1 voltage. If its less negative than spec its usually a resistor in the horz osc or one of the tubes. 73 Zeno LFOD ! |
