Here's the schematic, if you want to have a think now

As you can see, there are various values changed in the circuit for
the 12V or 24V options. I'm sure fairly simple mods can be made
for 66V. Operation is mostly the relationship between AN0 and
the PWM duty, other than that it's just keeping components in spec
