Hello,
I need a new knocker assembly for my Gorgar. Not sure which ones will work well for this pin. I have the Rottendog CPU/Driver board installed. I heard the old Williams knockers were very weak.
Will this work OK? https://www.marcospecialties.com/pinball-parts/500-5081-00
Thanks!
Yes, the original Williams Sys 3-6 knockers are kinda weak, just how they are. The original assembly is p/n B-8047, and I don't think anybody carries them anymore. Here's one on ebay, but not the correct coil. ebay.com link:
The original coil is a SA-2-23-850 with diode. Here is a pic of the one in my Firepower.

Just about any knocker assembly can be made to work.
Just ensure that the coil has a diode and that you wire it correctly relative to diode orientation (power goes to banded side).
