What IsSingle Ended Class A Tube Amplifier?
Audio amplifiers in mass
production typically use an integrated circuit to amplify the audio signal.
Even though modern audio amplifiers reproduce audio signals with less signal
distortion than their predecessors, some audiophiles prefer the "warm"
tone a tube amplifier produces when it reproduces an audio signal. Except
integrated circuit to amplify, many audio and power amplifiers sold for
personal and commercial use contain electronic devices called transistors.
Transistors came about as an intended improvement upon an older technology—the
vacuum tube, used as an amplifier component since the early 1900s.
One common type of
vacuum tube - the triode - is commonly used to create tube amplifiers. A triode
is so named because it has three electrical connections: the grid, the plate,
and the cathode. A triode can receive an alternating current - or AC - signal
through the triode grid connection, and can amplify the signal by application
of direct current - or DC - electrical energy across the triode plate and cathode
connections. A Class-A amplifier operates at an efficiency level between 25 and
50 percent. Therefore, a triode-based Class-A amplifier requires a high-voltage
(100-volt or more) DC power source to provide power to the amplifier. Unlike
transistor-based Class-A amplifiers, a triode-based amplifier also requires a
separate direct-current (DC) power supply for a cathode heater. Without the
cathode heater activated, a triode-based amplifier will not work.
While many transistor-based amplifiers are capable of
reproducing and amplifying a signal without noticeable signal distortion, some
audiophiles prefer the slightly distorted signal that a tube amplifier
provides.
There are two types of tube
amplifier output circuit: Push-pull output circuits that are wired so that the
output current is split and runs in parallel, the other is single-ended output
stages that are not split and run in a linear fashion. Single-ended tube amplifiers
can generate more power from less current. Single-ended tube output circuits
are used in both audio and instrument amplification. There is less distortion
in a single-ended amplifier because the output currents do not cross over.
A high cost effective and high quality single-ended tube amplifier had been hit the market by WistaoTechnology since two years ago. There are several models to be selected for customer. They are Class A, pure tubes amplifier, whose pre-amplifier adopt 6N3J tubes, and power stage adopt EL34B tubes, also its rectifier adopt 5Z4PJ tube, and the chassis is made of traditional black or Mirror Stainless Steel with silver.
