Quoted from metallik:How in the world is a dual-wound flipper coil overheating like that? Are they not cutting the power circuit voltage when switching to hold voltage?
Even on hold, temps rise, and that diverter can be on hold a LONG time. Stern seems to be machine-gunning their duty cycle with sub-millisecond pulses to achieve their magical almost-no-heat holds. I'm not sure JJP's hardware can go to that resolution, or if they even have that ability on the hold circuit which is separate on a dual wound coil. Spooky's duty cycle on hold is in the millisecond range and may be limited by the P-ROC hardware so they can't emulate Stern's approach (multimorphic care to comment on the lower limit of duty cycle timing pulses with their P-ROC hardware?).
