OEM manual provided all schematics, board layouts and component specs necessary to facilitate unit maintenance. All pages were clear and readable.

Good condition and quality. Hard to find anywhere in Internet, only on this site.

Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
