[sdiy] Yamaha CS-5 schematics

[Chris Strellis]

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
