I just finish a recap and transistor replacement on this Pioneer SX-9000. It does sound great but it wouldn't reach rated output before clipping. It started clipping at about 17 volts AC, reading across my dummy loads. Which is about 36 WPC. This stereo is rated at 50 WPC, which should be 20 volts AC. With the volume all the way up it does get 22 volts = 60 WPC. So it does have the power.
There are 4 pots on the main amp board that the service manual doesn't say anything about.
