Hello all,

I pulled a narrow neck K7000 out of a machine today. It's got a short in
the red gun (red always on).

Does anyone know if it's possible to use a narrow neck chassis on a wide neck
tube ? Obviously the neck connector will have to be changed. The schematic shows
only the connector pinouts are different so I'm presuming the neck board is
mostly the same.

The only other thing is my donor tube yoke will have to have similar H/V coil
resistance values.

Thanks,

JD
 
yeah, it's entirely in the neckboard.

the easiest is to swap the neckboard with a 10 pin. I've done this before. be mindful there's some variations of the neckboards where some won't mate with certain deflection boards. I think you can determine it by the R213 resistor if it's single or dual resistors.
