Default Yamaha MX-2 schematics and help needed

I've just bought a yamaha mx-2 used, and its works fine mostly, but the turn-on delay is very dependent on the time it was left off.

Once, I left it off for around 3 days, it took some 3 minutes before the speaker relays were closed! (normally ~30 sec, turn on once a day). I see no mention of this kind of behaviour in the operation manual....

Would appreciate if anyone has the schematics or service manuals available.

Thanks!

Looks like you have to replace some elctrolytics in the delay circuit. I don't have the schematics, but it should be relatively easy to locate the delay circuit.

They have schematics here: www.manualscenter.com, but not for free.
