CS50 schematics anywhere??

CS50 schematics anywhere??

2017-06-26 by jw_dewdney@...

Hi all... i'm new to the group.

I have a CS50 service manual i downloaded but can't seem to find any drawings in the package - it's only a long description of the concepts of the design. I was looking for a set of schematic and board drawings. Anyone have a lead on these?

Specifically I'm trying to troubleshoot a blowing upper fuse - and it's kind of hard to figure out without knowing which of the pins in the molex connectors are what ... so i can see if there's a short ...

Yamaha's old service documents are among the beautifullest technical prints ever. The schematics, the graphics, the typesetting, the yellowed paper, the fold-outs, the cover, the odd metal binding... just wonderful.

I have the original CS-50 service manual, and it's easily the classiest book in my library. :-)

PS: The CS-40M document seems missing on  http://therogoffs.com/cs80/
Thanks for keeping up the documentation work though!

well that too... though I was just referring to the quality of the scans... the CS50 documents I already had were pretty awful as far as reproduction goes
