Stereo tone control with
loudness and filter

Tone control circuit is used to
adjust the tones before entering the amplifier. Tone control over equipped with
a loudness and filter directly without using the switch to disconnected or
connected. Part of his filter that is C1 and R1 from ground to input , and for
his loudness on the R4 and C3 are connected to the input and then go to VR1. C2
and R3 go from ground to the input . After the input is set by volume or VR1
then procesed again by treebel ie C8 , R13 , R14 , and VR2 . Bass on R10 , R11,
R12 , C7 ,C8 , and VR3. For supply voltages has been given a stabilization in
Q3. See schematic below :

Part list :
R1 = 100K
R2 = 50K
trim
R3 = 22K
R4 = 15K
R5 = 1K
R6 = 4K7
R7 = 330K
R8 =
330K
R9 = 3K3
R10= 5K6
R11= 8K2
R12= 5K6
R13= 1K
R14=
1K
R15= 50K TRIM
R16= 50K TRIM
R17= 330K
R18= 4K7
R19=
47K
R20= 1K
R21= 4K7
R22= 2K2
R23= 100R
R24= 22K
C1 =
15n
C2 = 15n
C3 = 560p
C4 = 4u7
C5 = 33u
C6 = 4n7
C7 =
39n
C8 = 39n
C9 = 4u7
C10=4u7
C11=470u
C12=100u
Q1 =
C1815
Q2 = C828
D1 = Green Led

This tone control is suitable with 150W
OCL power amplifier type 036.But the schematic is mono, if you need a stereo
tone control you must duplicate the components  and
circuit.
