The LA-2A is a hand-wired, tube-based compressor. It uses an electroluminescent panel together with a cadmium-sulfide light-dependent resistor (which in the LA-2A's own terminology is called the T4 cell) to provide gain reduction. The properties of the T4 give the LA-2A its unique character by making it an entirely program-dependent design.

The correct value is "10 milliseconds", and this value is posted on the UA website. The LA-2A is an optical compressor, and optical compressors have notoriously slow attacks. The fastest available 1 millisecond, which is 100 times slower than the erroneous "10 microsecond" figure for the LA-2A. I'll post some citations when I have some time later.
The output amplifier was changed from a class A to a push-pull (class AB) design, based on the 1109 preamplifier, providing more output drive. The output transformer was changed to the B11148 type (already used in UREI LA-3A). Metering circuit now uses an op-amp. Revision G Not indicated 7053–7651
Uforia Audio Network (/ juː ˈ f ɔːr i ə /) is the radio broadcasting and music events division of TelevisaUnivision USA.

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.
A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. [1] It is an analog circuit with two inputs and + and one output , in which the output is ideally proportional to the difference between the two voltages:
XHLNC, which for its first six months was known as XHTNA-FM, was originally permitted to sign-on with a Class A 1,000-watt signal, broadcasting from a tower located in the Mount San Antonio area of Tijuana that had been used by other Califórmula stations. 90.7 is also the frequency for KPFK in Los Angeles, which operates at a grandfathered 110,000 watts.
