Quoted from MarkG:

Also, for those unfamiliar, Big Strike/Hot Line may be the first use of a dot matrix display in pinball. If you haven't seen it there's an animated GIF on ipdb at: https://www.ipdb.org/files/1245/Williams_1966_Hot_Line_Animated_Rollover_Button_Letter_Sequence.gif. Another excellent Steve Kordek innovation.

That is freakin COOL!
Thank you again Mr Kordek!

Thanks for the gif link!

Quoted from MT45:

See pic of my Big Strike score reel contact board. This is the “1’s” reel board. It looks like it has arcing to the point it has removed some Bakelite material around the contact areas. Can I just drip some epoxy in there to fill it in to provide a smooth surface for the 2 reel contacts to ride on?
It looks like the previous owner decided that liberal doses of WD40 would help the reels turn a little better and I am methodically pulling every component out and cleaning them.
Also the B-26, 800 coil on that reel was melted solid inside. Got new ones coming and wondering if this board issue might have been genesis of problem or if it was simply a stuck switch
Thx in advance [quoted image][quoted image][quoted image]

Bakelite looks burnt up for sure. I don't think it runs high enough voltage to be a problem, but make sure it isn't full of tons of carbon soot making it conductive before coating over it.

Crazy how that burnt up like that.
Best wishes on the repair

Can you fine sandpaper those coper pads down so they are totally clean on that disc? Shouldn't have any marks left...if you can.

Awesome! Yeah, I would try cleaning all those contact points and the big ring in middle all pretty before teflon lube.

Make sure points on all the fingers are clean and mating well as well
