I've performed some clean-up on the files section here at Yahoo!
Groups. The AN1x PDFs have been removed and replaced with
direct links
http://groups.yahoo.com/group/AN1x-list/links/ to the
AN1x, PLG150-AN and AN200 reference materials (PDFs)
provided at various Yamaha web sites. Hopefully this will better
serve the interests of the list.
regards,
Jon
