Just received my TNA yesterday! I'm looking to add the shaker and knocker, which I'm buying from pinball life, but I'm trying to figure out if I need to buy the expansion board assembly as well ( https://www.pinballlife.com/spooky-p-roc-knocker-and-shaker-expansion-board-assembly.html )
The descriptions on PBL say that each item includes everything needed, but searching this thread I've found images of machines with the expansion board installed.
Which it it? Thanks!
