I bought my 1990 Valley 7 ft from a concessionaire that had quit the business. Coin op was MIA so I just drilled a golf ball to fit on the ball release arm. Got tired of that so I removed the ball release gate which turned it into a free return, so I can now use any CB I want and spot balls.update: after a bit of trial and error, my table has been restored to Coin Operation, set for free play.
Purchased a new ball trap directly from Valley, as the original went MIA many moons ago.
Had to do some tweaking, as the last ball, sometimes gets hung up.
the biggest challenge ended up being the coin mech.
I originally sourced a 5 coin model, but it was slightly too big, to fit in the stock opening.
I could've modified the coin door, but i wanted to keep this as close to original as possible.
took a bit to track down a 4 coin model, that wasn't way overpriced, completely trashed. or both...
Also i learned there are two different sized coin chute extensions
The one on the left is for 1979 - later tables
The one on the right is for 1972-1978 tables
The coin op hole is still there but other than the cat sometimes crawling into it, no worries.
