I Bought a Sanyo (Otto) DCA-450 Amplifier From a used Audio Shop and was very cheap. After I brought it home and plugged some speakers and immediately found out that one side of the amp is not hearing properly, so I took it apart and found out that the transistors are missing and it has been replaced with an STK which does not support the voltage in the amp (around 78 Volts) If anyone of you guys got the manual or the circuit diagram for the DCA-450 Please Let me know.
This STK doesn't work with this amp anybody got any ideas on what to do to this amp please let me know.
