606BD 1.2 – TR-606 Bass Drum clone

This is an update of the 606 Bass Drum clone: version 1.2

Addition of an op-amp buffer output and correction of the trigger circuit (PNP instead of NPN for Q2)

The output buffer has a trimmer potentiometer (R23) for setting the output amplitude. Turn Clock Wise to increase the output, CCW to decrease. Adjust until distortion disapear (the maximum amplitude is when “Tone” potentiometer is set on middle position).
