Dear Friends,

Happy New Year to all!. I am working on a Pioneer A401 amp. Everything seems OK with this amp except that the right channel sounds slightly softer than the left channel. If the press the "Direct" switch, it bypass the bass, treble and balance pot but both the speakers sound balanced. I guess the power amp circuit is OK. I guess the problem is with the preamp circuit or the tone amp circuit. Can someone pls help.

Thanks

Carlosraj
