I had a flipper coil that buzzed when the flipper button was held down, and the EOS was working properly, so I got a new coil from Marco and replaced it. It still buzzes, even if I manually hold the EOS switch open with a large gap. What does this mean?

Thanks

I would try cleaning contacts.

Check your solder connections and make sure they are good. A stop and or plunger that is not flat will create buzz also.

This can sure be frustrating. On my Abra Ca Dabra it ultimately (after hours of checking various scenarios) turned out to be the alignment of the plunger with the coil stop. This can be tricky and the alignment tolerance between buzz & no buzz extremely fine.

Most Sterns do this as they don't have a true hold... Not that it is your problem in this case.

No need to replace the coil, the problem is in the coil stop.
