jhstewart9 said: Here is the DC coupled amp described in the April 1951 edition of Audio Engineering. There are simpler ccts published more recently. Click to expand... Coupling capacitors are C1 and C2, in power supply. Instead of being coupled through the grid it is coupled through the cathode. The only place where a coupling capacitor better ...

Audio Distribution Amplifier is a circuit which transfer signal from one audio source to many output with a facility of appropriate amplification. The project published here is of Audio Distribution Amplifier Circuit using LM324 is shown in figure 1, which is basically a low cost, low noise amplifier designed using one of the most popular ...
Regenerative Receivers

The audio amp. does not show a capacitor on the input because there is already one on the receiver's output. This amp is nothing special and many substitutes are fine. When the regen control is set too high, there will be a lot of squealing and whistling as the radio is tuned. When it is set too low, there will be no sensitivity.

Source: Operational amplifier High gain—when there are many the transistor so many gains. Easy—just add two resistors you so a good audio amplifier. Inexpensive—Now IC is low price than a transistor in the same working.. Do you want to use IC? In the list below, I show using three IC. First, the famous 741 OP-AMP, it is cheap and easy to get at all store near you.

And have Q2 is a constant current source circuit. The IC1-LF353 will act as the adjust the treble sound. And IC2-NE5532N serves as a fine bass voice. Because the normal tone control and pre-amplifier will work best well. When they drive a circuit with low impedance, and the load applied to high resistance.
