Gary;
This may be a different chassis we are talking about..
That resistor I'm talking about feeds the horizontal drive pulse from
the video/deflection chip to the horizontal drive circuit. Instead of
sending me the circuit, just send a picture of the chassis itself,
regarding the location of H/O and Regulator.
