This
circuit is an active STEREO tone control that will accept in its input signals
from 150 mV to 1V and provides in the output 0.5V to 3.5V. The distortion
is 0.02% and the frequency response is 10Hz to 25KHz. It can be used with
the kits 1023 and 1024 to make a complete STEREO Hi-Fi amplifier, without
much money.V18-30 VDCP.S. 1068PCB 52x100mm
