I am having a problem with channel 1(accoustic) of this amp. Channel 2, which is the 'electro" channel works fine. When I set the volume at about below 50%, there is totally no sound. When I start to increase the volume, approx at 3/4 of the full setting, suddenly the sound comes out. Then if I off and on, it works as normal but if I leave it off for more than 30minutes, then when I on back the amp, the problem repeats ( no sound at low volume). I tried resoldering the whole board (channel 1), but no difference. Can the problem be with the inverter IC (CD4069). Please assist.
