Quoted from canoncitypb:
I am considering a local DD. What should I look for to know if it will really hold up and has had its issues addressed? It is fairly expensive and I don't want to run into expensive problems down the line.
thanks for any help.
I'd suggest posting to the Gottlieb System 1-80 thread for more general System 80 buying advise. See: https://pinside.com/pinball/forum/topic/home-for-the-gottlieb-sys1-sys-80b-guys-yep-i-guess-it-a-club
Also check out the wealth of info on Pinwiki. Yes, it's quite a lot to take in, but certainly helpful: http://pinwiki.com/wiki/index.php?title=Gottlieb_System_80
For a short list I'd say you want a DD, or any pin for that matter, that is or has:
-a corrosion and hack-free board set
-a solid and zero water damaged cabinet. Look over every inch.
-minimal playfield wear. You'll usually see wear around the pop bumpers first
-working displays, all digits, all segments
-a clean, undamaged (or minimal damage) backglass. DD backglasses are very hard to come by.
Learn how to run the diagnostics.
If it's working when you go to buy it you're in good shape. If it's not working be prepared to haggle big time. System 80 repairs don't have to be expensive, but if you have to hire someone to fix it you'll be kicking yourself if you didn't figure it into the price you paid.
And for full disclosure, here's the rough list on what I put into my non-working, barn-find DD:
Cabinet was solid, playfield good with just a bit of wear around the pops, backglass heavily flaking, dirty, heavily scratched playfield glass, spray painted and wrong type legs.
(All estimated and/or rounded up)
Base game: $300
used backglass: $100
New legs, bolts, levelers: $60
Playfield glass: $100
Pop bumper caps, skirts, drop target set, rubbers: $75
Misc electronic parts: $25
Repro manual; $25
I think I got mine to boot after cleaning all connectors on the boards. Some displays were out requiring a bit of troubleshooting/repairs, but nothing major. Did a ton of cleaning and swapped all the bulbs out with new. Total time maybe 8-10 hours, working at a lazy pace with frequent beer breaks.
Good luck on your hunt.
