Tube Mic Pre-Amp

Posted on Feb 6, 2014

Here the simple audio mic pre amplifier circuit based on single IC LM358. The circuit is very simple, inexpensive and easy to built. Component Parts List: R1, R3, R4 = 10K R2 = 1K R5 = 100K-1M Potensiometer C1 = 0. 1uF C2 = 4. 7uF/16V IC1 = LM358 dual op-amp single supply Mic = Electret Microphone. This is a simple and low cost Tube Head Vacuum Tub

e pre-amp circuit designed bu PAiA electronics: Vcc - Pin 1 IC1 +12v - Pin 8 IC2, IC3, IC4 -12v - Pin 4 IC2, IC3, IC4 Ground - Pin 8 IC1 IC1 - 4049 CMOS Hex Inverting Buffer IC2, 3, 4 - 5532 Dual Low-Noise. This Tube Sound Fuzz circuit is taken from the book of Electronic Projects for Musicians by Craig Andertons. This circuit applies a CD4049 Hex inverter, which consists of six inverting units, only two are being used in this circuit, so the others are disabled by connecting their inputs to the positive voltage source and leaving. The following diagram is the circuit diagram of 20W power amplifier which build based tube component EL34. EL34 is very famous tube and great for power tube amplifier. The circuit above is complete circuit contains tube amplifier circuit diagram and power supply circuit diagram. To make the stereo channel amplifier, build the similar amplifier circuit. The following circuit is Tube Distortion Pedal for guitar effect. The circuit designed by Ron Black. Notes: IC1 : 747 dual op-amp, other ICs may be substitued but pinout will different. You should check the datasheet IC2 : LM340K-12V Voltage Regulator All resistors are 1/2 W Bridge Rectifier - Full wave bridge recitifier, 50 Volts, .
