I got what i think is a flyback transformer from an old packard bell
monitor, but none of the wires are labeled, so i don't know where the
input and output are. i have 4 pictures of it. the bottom of it has 2
isolated pins and 10 in a horseshoe shape. i'm guessing the 2 that are
separate are the input and the red one sticking out the top is the
output and the other pins in the horseshoe shape are taps or something.
there are also 2 knobs on the back of it labeled "focus" and "screen.
what do they do? the pictures tell it better. could someone also direct
me to a site that has a 555 driver schematic for it? also, can you use a
flyback to power a small TC or do you just use it for plasma globes hv
tricks? thanks a lot. here are the links
