1975 Atari Crash 'N Score Restoration
Majoraslayer:
Well, I took all of the electronics and such out of it, as well as the front overlay. In the process, most of the cab fell apart. The sides are each still intact, so I can get the measurements and scan the sideart. Scanning the artwork should be even easier now; I can just lay the side on a workbench.
I am a little concerned about the board. Everything looks fine except for a big, ceramic resistor next to that huge heatsink. It has cracks in it, which makes me wonder if it might be bad. I'm SO glad I found that service manual; it has very in-depth schematics, so I should be able to track down the value for it to replace it.
Level42:
Good thing you took everything out ! It wouldn't have surprised me if it would have collapsed and at least damage the monitor that way !
I've seen cracked ceramic resistors that are still fine by value, but there can be doubts about wether it still will dissipate the heat enough....
Majoraslayer:
The area on the underside of the board, beneath that huge heatsink and ancient IC, is fairly black and brown from the heat. It would be nice if I could upgrade that heatsink, as its obviously still getting VERY hot. Its right next to that ceramic resistor too, so that could possible be it. I'll post pics later of that, as well as some more in-depth pics of the components.
Oh yeah, it turns out that it wasn't missing a pedal. The panel that pedal was bolted to was flipped upside down for some reason, I guess as it was just jammed in there for storage. It appears a rat made a nest under it too :dizzy:
Majoraslayer:
Well, I did some work on the power supply today. I sanded a lot of the rust off of the transformer and other metals parts, bolted everything onto a new piece of plywood so I could ditch that nasty rotten trash, and cleaned off all the cobwebs and junk from that area.
I also cleaned up the monitor, plexiglass, and bezel.
It turns out I'll need replacement speakers. Does anyone know of a good place to get cheap replacement speakers with the right impedance rating?
Level42:
And do a search for "speaker". Not sure if they're the right size. Don't worry about the impedance, not that important.
