the SA02 has a single positive supply, the output is an H bridge
..damn, keep forgetting about having to drive the yoke in BOTH directions.
the other guy helping me with this at work and I were wondering the same

..and we have noticed the current to voltage power resistor :-)
Zonn, have you ever taken a scope and measured what the maximum voltage
is at the horiz and vertical deflection coils of a G08 (driver side,
obviously..)
