Quoted from SGSA:Sorry docquest - I somehow missed your post 5 days ago. We will have two options available for headphone kits that will work with Spooky machines. There will be our traditional headphone kit that goes in the coin door DBA like the picture you posted and we will have an under cabinet mount kit as well so whichever coin door you have you'll be able to install one of our kits. Let me know if you have any other questions.
Also, someone mentioned having a custom painted coin door - we work with those as well, no extra charge. See here for more info https://pinside.com/pinball/forum/topic/pinnovators-hp-kit-for-spooky-american-pinball-vp-cabs#post-5407597
Thanks.

Any idea on a timeline when this will be available? I'd love to add one to my TNA.
