I have just made my first GainClone chip amp with LM3875. The kit is from audiosector. The problem whitch i have is that when I turn the volume of my NAD C 320 BEE, which i use as a pre from pre-out, a little bit higher it occurs hard clipping. Should I tweak the PS witç bigger caps? I only use two 10ìF caps that came with the basic kit...
