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!!!!!!
The Service Manual received was helpful. Good copy of original document.. I recomend all of my friends about this technical page.
