There were 2 different #s on the output transistors, but he said they started using all 44s later and I could just replace them all with 44s and it would be fine.<BR><BR>I hope this works, I am ...

The amp features McIntosh’s new DualView Power Output Meter which stacks two meters in a single window. One of the meters displays the output of the 300-Watt vacuum tube section while the other ...

Second, the RF amplifier is directly connected to the DC power supply. At the positive half cycle of the drive signal, transistors 1 and 3 turn on, forming the positive half of the waveform at the ...

Members can download the PDF ebook. One day, back about 1966, I was going up the elevator at 285 Columbus Avenue in Boston to look at some production problems on Philbrick’s fifth floor. And who ...

They typically use transistors as the core amplification component along with a supporting cast of resistors, capacitors, inductors, wires and transformers to make the whole thing work. But it is the ...

While choosing an op-amp buffer, some sources of negative supply were considered, because the buffer op-amp had to provide true zero voltage on its output. In reality, a typical rail-to-rail output op ...

By contrast, an analog amplifier that weighs less may use a smaller transformer with inadequate capacity and fewer or thinner heat sinks (heat sinks look like radiator fins and are used to dissipate ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables” was published by University Minnesota and Cadence. Abstract ...

The amplifier is a very old-fashioned, single-ended design with an output transformer. The transistors in question are the now-archaic germanium PNP devices that had probably already been ...

Powered by a factory-wound toroidal transformer driving a set of high-current output transistors, ... The amp uses an ESS ES9039Q2M Sabre DAC in pursuit of a low noise floor and a wide, ...

In addition to the rare 300B, there exist a great number of tube types. Electric-guitar amps, for example, routinely use vacuum tubes because their warm, engaging sonic signature can’t be ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...
