By 1977, all of Crown's tape recorder products had been phased out. [2] In 1979, Crown introduced the PSA-2 & SA-2 power amplifiers with analog computer control of transistor performance to maximize output characteristics. [2] The FM-1 stereo radio tuner was praised at the Consumer Electronics Show. [2] In 1981, the FM-2 with digital tuning was ...
A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .

Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus One hi-fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
At the time the only other WTB amp was the WTB1000, which was basically a WT800 with selectable 8-band graphic EQ and one semi-parabolic control. The only similarity between the WTB1000 and the WTB400 and WTB700 was the single semi-parabolic control that could be turned on or off. Otherwise they were entirely different pre-amp and power sections.
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 .
By 1965, the demand for Sundholm's amplifiers had increased to the point where the family garage could no longer be used as the manufacturing facility. At this point the Sunn amplifiers still relied on the Dyna power amp circuitry, reworked to fit Sunn's own chassis but still employing Dyna produced and branded transformers and the same ...
