[sdiy] lisajou on tv

[John L Marshall]

The horizontal oscillator is usually also the driver for the flyback
transformer, the source for the anode high voltage.

I would connect another set of coils in place of the coils that you want to
use.

Please, do not forget that the CRT is a near perfect capacitor. It can hold
a charge that can kill you.


Take care,
John
