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.
Information was accurate and very helpful.
However the continuity made it a little difficult to follow from one page to the next.
Very very good as usual very trustable site. Perfect!!!!!!
