PRE AMP CIRCUIT 5-15VDC 1/2W SINGLE SUPPLY - READ MORE
I BUILT THIS USING A 741 OP AMP FOR A PROJECT I WAS WORKING ON.
I NO LONGER NEED IT. IT HAS BEEN TESTED AND WORKS GREAT.
YOU CAN INPUT 5-15VDC IN ON THE + AND - TERMINAL. PLEASE NOTE
THE CENTER TERMINAL IS UNUSED. ON THE OTHER TERMINAL YOU
INPUT THE AUDIO SIGNAL AND RETRIEVE THE AMPLIFIED AUDIO SIGNAL.
THIS SIGNAL/TERMINAL SHARES A GROUND. THE GAIN IS APPROX 40-100 DEPENDING
ON THE SUPPLY VOLTAGE. YOU CAN ADJUST THE GAIN WITH THE TRIM POT.
I CAN GARENTEE THE CIRCUIT WORKS, BUT I WILL NOT RESPONSIBLE IF
YOU BLOW IT UP. USE AT YOUR OWN RISK. I CAN BUILD MORE OF THESE UPON
REQUEST, BUT IT MAY TAKE TIME.
