I am making a habit of restoring really old poorly scanned schematics from factory units. And archiving them in Audiokarma for people doing "Google Searches"

I take old nasty schematics, and clean them up in Gimp to be as clear, and precisely drawn as possible. Repairing "Pixel by pixel"

This schematic is as bone stock as it gets, but it can be used to re-create modification or alterations later if somebody wants too. As the only Schematic out their for the 8302 are pretty low res and low quality.

I have this little Amplifier, Which I converted to my own needs. And as tiny as this amp is, its absolutely wonderful in sound! This thing is so tiny, I could probably fit the entire Amplifier inside a large coat pocket.

This particular one is a Rosy Gold orange color, and is Cadmium Plated. Unfortiatly the plating seems to oxidize extremely quickly, it needs weekly polishing if I am to keep the chrome shiny surface.

Though Cadmium is toxic, this should be done with care and awareness of that fact. If its not peeling off, your probably ok. Just wash your hands after polishing.

Nice, that is really clean. I'll have to check out the Gimp program. I frequently come across schematics that look interesting but are unreadable. Usually, the issue is that the details are too small to read and when you try to enlarge them the details get really blurry. Sometimes printing and using a magnifying glass helps but usually not.

Would Gimp be useful in those situations?

I'm not sure what version of the 8302 that you found to be low res and low quality, though. FWIW, here's the Sams in pdf, which can be enlarged to show detail. It's not as clean as the one you posted but I wouldn't call it low quality compared to many I've seen.
