Many thanks!

Pretty complex procedure!...looks like i'll be spending two weeks
adjusting it anyway! :)
This unit hasn't been properly taken care of for at least 10 years, it
was bought as "non working" for about 1500us$!

Everything you need is at www.cs80.com, Crow's site, and also
http://personal.inet.fi/private/matador/cs-80_adjustment_procedure.html.
 I also run a CS80 group on Yahoo
(http://launch.groups.yahoo.com/group/yamahacs80/) that has links to
lots of great sites and has lots of discussions about CS80
repairs/tuning.  Many CS80 experts are in the group.
