The second amplifier released was the Phase Linear 400 with 200 watts per channel. It shared the same distinctive brushed aluminum, dual VU meters front panel style as the 700. It retailed for just under $500. [1] The next product was the Phase Linear 4000 Series Auto-correlation Pre-Amplifier introduced in 1973 and manufactured through 1978.
A linear circuit is an electronic circuit which obeys the superposition principle.This means that the output of the circuit F(x) when a linear combination of signals ax 1 (t) + bx 2 (t) is applied to it is equal to the linear combination of the outputs due to the signals x 1 (t) and x 2 (t) applied separately:
A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .
The noise voltage density of a given valve is a function of frequency. At frequencies above 10 kHz or so, it is basically constant ("white noise"). White noise is often expressed by an equivalent noise resistance, which is defined as the resistance which produces the same voltage noise as present at the valve input.
Electrical diagrams for switchgear often have common device functions designate by standard function numbers. Another type of diagram used for power systems is a three-line diagram. For analysis purposes of a power system, from the one-line diagram, if the system is balanced, an equivalent per-phase (or single-phase) schematic diagram can be ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

[31] [1] While the paper was waiting for print, the magazine had published the new version of Cocking's Quality amplifier. Cocking, as the technical editor of Wireless World , certainly had precedence; according to Peter Stinson, he was sceptical about the Williamson amplifier, believing that his own design needed no further improvements.
