    Hello,
    I am using a Sansui 350 for my garage stereo. It sounds great. No problems. I thought I'd check the bias and internal offset, but can't find any info. on it. I've downloaded the manual, but no instructions. Can anybody out there give me some help?

    its capacitor coupled output so no dc offset as such .. but has adjustable centre voltages .. basic setting is collector of tr811 should be about half of tr809 collector voltage .. it can be adjusted with vr801 . that is just one channel .should really be done with a scope to achieve equal clipping when its set right .
    idle bias can be adjusted with vr803 for that same channel .. i have no idea what it should be set to .

    there are lamps across the fuses . i have no idea what those are for . might be set bias or just to let you know if a fuse blows . maybe another similar model might have the correct instructions .
