I posted this to facebook as well, but didn't get much in the way of responses...

I recently picked up a Bally Hay Ride (it's the add-a-ball version of Harvest). One of the coils has a break inside... there's no resistance on the ohmmeter. It's the latching coil for the tilt-- when I hold it in with my finger, the game starts and plays as normal.

The coil in question is a KKN-332 (cross reference C-7800-332). PBR is out of stock. Marco is out of stock and doesn't expect it in for 60 days. I reached out to one of the coil manufacturers, but haven't received a response.

Any of you guys have one, new or used, that you'd sell me?

Thanks in advance!

Bump. Surely someone has a parts machine kicking around...

Thanks. I actually already purchased a G-33-2800. That post is incorrect. The ohms of the coil is correct, but the form factor is off-- the bobbin of the G-33-2800 is taller than the KKN-332. It might work in some applications, but it won't work in this one-- it won't even fit into the slot in the switch stack.

Edit: To add... shipping from Canada will be prohibitively expensive, if it's permissible at all right now. This coil was used on a ton of games, so I'm not sure why I'm having so much trouble finding one. Going to research and see if there's a Williams or Gottlieb equivalent that I might be able to substitute.

Hmm... let me research and see if that will work. How tall is the bobbin, without the metal part? the KKN-332 is .71 inches

Nothing to apologize for! The general shape and size are right, the ohms are right... it's just the bobbin height that's off. Like I said, there may be applications that coil would work for, but this isn't one of them.

So... I wonder how important the ohms of the coil are for these applications-- anyone know? I just found a Williams M29-1000 in my stash, but it's only 15.6ohms. The bobbin is .0020 taller than the Bally coil, and drops right into the slot in the bracket... but the metal part sticks up a little further (too far to allow the coil to pull in and close the switches). The metal part isn't removable like the Bally coil- it appears crimped in. I could file it if there's a chance it would work.

Thanks. It's a continuous coil-- the tilt relay, which releases when the game tilts.

It actually worked... the game started, and everything operated as it should. The Williams coil was *very* noisy, and the cement resistor in that circuit quickly got smoking hot. So it's back to the drawing board.

That might well work. I looked quickly at lunchtime, and I was having trouble finding specs for that coil. I'll do some more research after work.

Ok. I figured it out. That coil isn't going to work.

Thank you for offering though!

7/8 as a decimal is .875. The G-33-2800 coil that doesn't fit height-wise is .86-- so yours is even taller.

Back to the drawing board. Hopefully someone with a parts game will see this thread. *REALLY* want to bring this game back to life! May make a temporary wedge to hold the relay shut. It will effectively disable the tilt, but it will let me start a game and troubleshoot things until I can find a coil that will work.

For future reference, KKN-335 will work as a replacement-- at least in this application.
