After building meyers PWM and VRC (volt regulator) i finally hooked it up to the scope.
and boy was i suprised!!!!!
all components are to spec, even finding the now obsolete IC's
sorry i didn't work out the frequency, i will post the scope setting if someone can work it out.
it actually seems to be squarewaved, squarewaves, if you look closely.
this is then imposed over the hish voltage with an optocouple and SCR. before hitting the VIC.
I will be posting video my progess and experiments on my you tube channel.
