So I am working on my brother's Williams Olympic Hockey. I've had it for several months and one of the last issues I'm trying to fix is the animated puck behind the backglass. Doesn't always reset and advance properly. Upon disassembly, I find the spring loaded fingers are badly worn and have resulted in a groove being worn into the contacts on the wiper plate. The grooves seem to be causing the mechanism to bind and not function properly.
So I have two questions.
Where can I find replace mentioned fingers (if that's what they're called)?
What (if anything ) can be done about the grooves?

Thanks for the reply.
I have no idea where I'd find a replacement board. Think I might try to recondition this one.
Not a lot of experience with silver solder.
Looked out on eBay and saw many different types of silver content, core type, etc.
Any recommendations ?
Thanks again!

So is it a rosin core type or a solid core ?
Looking online and not too sure what would work best for this application. I see listings silver bearing solder . Is that what I need?

I just sent him an email. Hopefully he will be able to help.
Thanks!
