Build a preamp that I want to use to take a 1/4" keyboard line level signal and drive a Leslie 147 amplifier with it. I want to build the preamp using a 12AX7 and 12BH7 based on the design of a Hammond Organ preamp. Here is the schematic to the Hammond AO-28.... -
I build the CAT SL1 preamp with the attached schematic Noted that the gain of this circuit has about 26dB. I noted that the new SL1 have an option.... -
The +/- 3 dB point for the treble is about 2, 5 KHz, with about 12 dB boost/cut at 10 KHz. Perhaps you should check the wiring (again ) or perhaps componentvalues Do you have access to a signal generator yeah i checked wiring and components again and again,.... -

This be Pre Mic circuit or Microphone preamplifier circuit model 2 CH. By this circuit uses integrated number circuit NE5532 or LF353. It perform enlarge sound signal from Dynamic Micro phone give the power goes up for subsequently submit to go to still.... -
This be simple Preamp circuit. It can take sound general signal AUX and a signal from Microphone. For enlarge sound signal at the beginning. By use op-amp IC.... -
When you want to enlarge sound signal from all source before costume amplify. Usual use Pre Amplifier or Pre Amp. Today I begs for to suggest again the one circuit. That interesting because of use Transistor just one ( the number replaces many the number.... -
A good quality preamp tone controls, a total of three circuits. We choose to use the NE5532 is main so interesting IC, because the ultra-low noise properties, it is commonly used in many fine audio. But these circuits are old. I have a circuits of friends..... -
This tour, available in Stainless DIL 8 legs, can measure 4 analog voltage independent between 0 and 5 volts, and send the result of this measure in the form of four characters on a standard asynchronous serial link. Its serial output is di.... -
This microphone preamplifier electronic project is based on transistors and is capable of about 70dB or more gain at audio frequencies. Gain of this circuit is approximately equal to the product of the hfe of the both transistors times in the ratio of the.... -
This simple microphone preamplifier is based on the LM318 op amp. The LM318 op amp is operated as a standard non-inverting amplifier. Resistor R1 provides an input path to ground for the bias current of the non-inverting input. The combination of R2 and C2.... -
This microphone preamp schematic electronic circuit project is designed using the OP37 operational amplifier manufactured by Analog Devices and is effective, fixed-gain transformerless microphone preamp which amplifies differential signals from low impedance....
