looking for service manual for accuphase C-230

I need a service manual for my pre-amp . lately when i turn it on ,one side powers up first then about 15 seconds later the other speaker comes on . talked to my tech , he said would be much easier to fix with a schematic (not flying blind). If you have one or would be willing to send scans . would be much appreciated!
Its hard to find the schematic for certain accuphase amps, try emailing accuphase labs hopefully they can help.
