Have a look at the original manual, one of the last
pages have a full specs sheet with all the in/out voltages..maybe that helps. I
have a CS-5 myself and the manual is actual quite good. All those cute drawings
:)
If the direct link doesn't work, click to
Electronic music instruments, then change to Synthesizers (combo
instr.)
and you'll find every yamaha manual ever released
in PDF formats. Can't find any tech manual anywhere.
Try a google search. Most synth manuals are scanned
and available for free, you shouldn't have to trade or pay money for a paper
manual these days.

Subject: [vintagesynthrepair] Yamaha CS-5
schematics
Hi,
A plea for help\information.
Well it
looks like the transformer has gone on my newly acquired CS-5
and judging
by the repairs not for the first time either!
The part no. is GA81411
which doesn't ring any bells with Google.
What I'm thinking is
replacing the whole PSU section with a bought in
switch mode killing
several birds with one stone - ageing Jap caps
any one?. Now I need
to know the output voltages that a CS-5 likes.
I have a CS-10 and
corresponding schematics but this needs +15V, 0, -
15V and +10V. The
CS-5 seems to need just +/-15V. Can anyone
confirm this?
Better still anyone have schematics for a CS-5, I can
trade other schemos
for it if necessary.
Best regards
Chris
