Akai X-150D - real schematics and FF/Rew cam
Does anyone have the actual electronic schematic for the boards in the Akai X-150D? I have the service manual, but there are no schematics in it, just some bad photos of the boards One channel seems to have much less gain than the other and it would be nice to have a set of schematics so I could troubleshoot.
Anyone know if there is any amplification done by the play/record switching board?
The electronics look pretty simple, but troubleshooting without a schematic will be a pain.
Also, does anyone know of a source of the diecast "cam" under the Rewind/Fast Forward knob. The one in the Akai 150D I just bought seems to have disintegrated. Really weird. It just seems to have crumbled apart. Other similar cams in the deck look perfect, but this one looks like it was hit with battery acid, roasted in a fire and exploded! Failing a replacement does anyone have an accurate drawing or good photograph of it so I'd have a chance of machining up one myself. So much has broken off this one it's hard to tell what's supposed to be there!
