This Split stereo signal circuit model to are simple at use in fining wideness of a signal stereo. Which be valuable very for an earphone stereo. or the system that the opening between a loudspeaker too much.
This is TDA2009 bridge amplifier circuit BCL 18W,Supply volt = 23V 2A, it is 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number.
Here is Class A amplifier circuit. It have good sound Distortion-free. First use main are transistors only. Second: 5W output use IC-low noise IC,MJ2955 power transistors [...]
