That's crazy... No way he gets that.

Hey since I am on here... I have a question for you guys. Have any of you worked on older 80's Bally Pins? My biggest issue (and it is more of an annoyance) is the fact that the sockets seem to be made so cheaply that the bulbs will lose connection when the machine is vibrating from flippers to pop bumpers. Very annoying. At anytime it feels like the damn thing has one or two bulbs out. I have to take off the glass and just readjust the bulbs to get them to light back up.

Great job :applaud:

Good thing I don't have the space for those too!

Does it use the 555 bulbs? If so, go into the socket with a jewelers screwdriver and bend the contacts so they keep a tighter grip on the bulb. On the bulb, bend out the wires so they stick out more when you shove it in the socket.

If it's 44/47 sockets, wrap some sandpaper around any skinny cylindrical object, shove it in the socket, and spin it around. Then use some pliers and give them a squeeze to make them slightly oval.

I've never had to replace a socket ever. I'm surprised there's such a huge market for them to be honest.

:cheers:

Lamp sockets yes can be cleaned and tweaked with an abrasive stick. But that doesn't fix the problem, it only prolongs it, once the plating is compromised it will deteriorate quite rapidly the second time not to mention the base metal is less conductive than the coating, the heat and electrons work together to find the least conductive path and carbon up what is left effectively destroying it finally. Diodes too (if applicable) fail much more often than one might think and are usually overlooked in a quick fix and certainly doesn't help ghosts and flickers with a LED setup. and finally if the bottom of the holder spins, or the contacts are green it is flat out shot, you will get intermittent flickers at best.... I find it easier to just change them out for new rather than chase the same problem perpetually over and over wasting a bunch of time. (although there can be like 200 or so in a machine and can get spendy quite fast)...IMHO :-\

I've got a couple of games I've owned over 10 years. One of them from 1968. If my method caused rapid deterioration then I guess I'm in for a headache in the next century or so.
