The Silvertone amplifiers manufactured by Danelectro in the mid-1960s have become the most popular among guitar players for their great tube tone and Cold War-era styling.

Who made Sears guitar amps?

The bulk of Sears amps (and certainly most everyones favorites) were those great sounding, stylish, funky sound machines manufactured by Danelectro.

Who made the first amp?

Lee De Forest The first audio amplifier was made in 1906 by a man named Lee De Forest and came in the form of the triode vacuum tube. This particular mechanism evolved from the Audion, which was developed by De Forest. Unlike the triode which has three elements, the Audion only had two and did not amplify sound.

What does op amp stand for?

operational amplifier An operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port.

Why it is called 741 IC?

IC 741 Op Amp (Operational Amplifier) It was first manufactured by Fairchild semiconductors in the year 1963. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin.

Why IC 741 is used?

It consists of two inputs and two outputs, namely inverting and non inverting terminals. This IC 741 Op Amp is most commonly used in various electrical and electronic circuits. The main intention of this 741 op-amp is to strengthen AC & DC signals and for mathematical operations.
