Hello everyone. I’m hoping to make my Black Hole and Haunted House Pinball’s have a much louder knocker. The original coil is an A-5195 (11.6 ohms) and I’m thinking about changing them to an A-4893 (2.1 ohms). Any ideas if this would make much difference, or harm the MPU or driver boards due to the extra power draw?
I don’t want to make any crazy mods by adding springs or moving the knocker to the backbox etc, just update the coil if it will work.
New! Dark mode!
