Quoted from lopazopy:Picked up a High Speed as my first pin 2 days ago. Like most people buying their first pin, I think I slightly overpaid for the condition, but oh well, I'm happy with it. With little free time this week, now the dilemma is do I test/clean/fix the small things, or do I play it until my fingers bleed? Obviously I'm choosing the latter
My 2 cents. If it isn't smoking or the playfield horribly damaged, make sure the balls are relatively clean and play. Only way you are going to find out what is wrong. Then make a list of the obvious things that you want to update. LED's, rubbers, weak flippers etc... Then go through the check list. Take lots of pictures so you can put it back together. Be advised that no matter how careful and closely you look at things, you will miss something or break something putting it back together or change your mind. Book mark your suppliers. You WILL order several times.
I've been working on mine for about 6 weeks now, off and on. Getting ready to put the playfield back into it and fire it up. Praying for no smoke or sparks and lots of bright lights.
