i have replaced all capacitors with correct values but it sounds weird

I was curious if you'd have a high resolution copy of the service manual or the schematic diagram available? Google only seems to return rather crappy scans.

 

But to go through the typical motions: How did it behave before you replaced the capacitors? Are the voltages within the correct range listed in the service manual? Additionally, did you replace the capacitors with the correct type? It can be quite important on some of these devices that the capacitors have the correct parasitic properties, so only replace film capacitors with film capacitors, electrolytics with electrolytics, and so on.
