Hitachi HA-3800 AMP Issue
« on: January 05, 2013, 03:08:57 PM »
Hello,

Right STK Output was burned out. It is changed. After the change of the Right STK Output (STK8250), the left and the right channels are very quiet. I have changed the IC HA12002 but the condition hasn’t changed at all.

When I was examining the circuit board right after the Volume Potentiometer on the board it obtained a normal power level.

Any help will be really appreciated.
