Default Yamaha A-400 schematics/bias needed

I know a manual is available from Schaltungsdienst Lange, but the amp's old (1984) and suffers from various things (bass equilizer dead, one channel gone completely) so I don't want to pay 20euros for things I'm not shure I will be able to fix...

Does anyone have a schematic he could mail me? One of the bigger models (a-500, a-700) might work, too...

And any info on the bias?

Thanks in advance,
Matthias

Hi hiwiho,
I was going to email you, but I can't through the board. PM me. I have a zip of the A-700 that may help you.
