Stereo Pre-Amplifier with NE4558 DIY Kit

Components Kit + Generic NE4558 IC + PCB 

NE4558 Pre Amp is specially designed for the STK Power Amplifiers (IC). Although it’s compatible with even transistor amplifier or any kind of power amp. If you using one power supply for both pre amplifier and power amplifier, connect only +V and –V lines. Ignore the 0V line. Pre amplifier get 0V through “G” Line when connect power amp and pre amplifier (Output line of the pre amplifier with input line of the power amp). If you use separate power supply for power amp and pre amp you must connect all the +V, -V, 0V Lines. Power supply must be dual channel and voltage must be 15V- 0V-15V or above.
