Quoted from RA77:
Can you measure current draw on coils as part of your testing Vic ?
Hold has to be minimal right ? Guessing same coils used in Spike 2 if so, I can only guess there must be a sweet spot that Stern has found/produced in the drive circuit ?
Thanks for your efforts Vic.
I'm lucky not to play long enough to experience fade, but I could imagine how much it must suck. Pretty unfair for tourney players too I reckon.
Yeah, there's a lot of stuff I want to measure (playstyle button frequency, hold frequency, current, etc) to try to answer the "why" some arrangements perform better than others, and some flipper coils get really hot fast while others only get moderately hot or take a long time to heat up. But for now, I'm trying to get the kits adapted to all the major platforms first, then try to answer the bigger questions. A JJP kit will be the third platform, then I have older Stern SAM/Whitestar and B/W to do.
Stern uses smaller coils than something like the 11629. 219F would destroy Stern coils, but the 11629 on GnR powers through it, a little weaker, but still working. But something is different about the Spike hold pulses because there's almost no heat added while in hold. That's the biggest mystery so far. I would think dual wound bally/williams coils could compete with that, but no. They continue heating up when held on the machines tested.
