STK4241V 120W stereo amplifier
This Home Stereo Amp is equiped with STK4241V wich is a thick film hybrid IC, AF Power Amplifier (Split Power Supply) (120W+120W min, THD = 0.08%). STK4241V has some features like:
• Muting circuit built-in to isolate all types of shock noise
• Current mirror circuit for low 0.08% total harmonic distortion
For this 2x120W home stereo power audio amplifier we use a single monochip STK4241V to obtain up to 120W for each channel.
Amplifier home stereo components:
R6, R22 – 560 ohm / 0.125W
R1, R24 – 1K / 0.125W
R9, R10 – 1K / 0.5W
R7, R18 – 4.7K / 0.25W
R8, R19 – 4.7K / 0.5K
R2, R5, R21, R23 – 56K / 0.125W
C7, C17 – 3pF ceramic
C2, C20 – 470pF ceramic 50V
C6, C16 – 1nF 100V
C11, C12 – 100nF 100V
C1, C19 – 2.2uF 50V
C5, C15 – 1uF 63V
C4, C10, C13 – 10uF 63V
C9, C14 – 47uF 63V
C8, C18 – 100uF 16V
