Transistor Organ by 2N4891

This simple circuit can provide hours of enjoyment as you learn tunes, play duets or just make some really weird sounds by pushing all the buttons at once. You have probably seen this ciruit before, it is fairly common. I have seen it in several books. The best thing about the circuit is that you can tune each individual note, or go to a whole new octive by changing one capacitor (C1). Because of this, it is possible to from an entire Transistor Organ ensemble. Why you would want to do this is anyone’s guess…

Single IC Organ By IC NE556

Single IC Organ By IC NE556
When you will think to build Single IC Organ Circuit the some one. I begs for to advise this circuit , because use IC NE556 or LM556. Which within its structure is like have the integrated circuit IC 555 arrive at 2 together follow my circuit. Control by Keyboard contacts and SW1 Tremolo ON/OFF as a result can choose music pitch that can want.The detail about mini Organ Circuit the this. Can see in circuit picture sir.
