Quoted from flipnout1:
Looked at a couple of Skee Ball games at lunch today. How do I tell which model they are. In a local pawn shop for sale. Two work and one for parts. The one I played looked like some of the bulbs in the display were out. From the little research I've done that seems to be common. If its a LED however that can be expensive. They don't know if they have the keys or not so couldn't do much looking inside, etc. They are supposed to call me on Monday. I went to the Bay Tek site and it looks like parts for the newer versions are available. Does anyone know of any other parts, manual suppliers for them other than maybe Brady? Any info would be helpful
Here is a pdf for a model S. From what I understand the model H was built from around 80-88 and the S from 89 on. Check the metal tag behind your back glass. https://www.google.com/url?sa=t&source=web&rct=j&url=http://arcarc.xmission.com/PDF_Misc/Skeeball%2520Model%2520S.pdf&ved=0ahUKEwjfjOjT9ofSAhWGWSYKHdEwBFIQFggtMAM&usg=AFQjCNHsNISdbw-ARTzSAgujdiFXgViwcg&sig2=Ew2CXEu87ohjquXPV2XbJw
Also, check out this article. It will explain all of the differences between the S and H on page 3.
If some of the segments aren't lighting up on the numbers it's probably just a few burnt out #73/74 bulbs. They are about 30 cents a piece.
