The 1959 (Marshall's identifying numbers are not years of manufacture), produced from 1965 to 1976 (when it was replaced by the 2203 "Master Volume"), [1] is an amplifier in Marshall's "Standard" series. [2] It was designed by Ken Bran and Dudley Craven after The Who's guitarist Pete Townshend asked Marshall for a 100 watt amplifier. [3]
In 1967, Marshall released a 50-watt version of the 100-watt Superlead known as the 1987 Model. In 1969, the plexiglass panel was replaced by a brushed metal front panel. Other early customers included Pete Townshend and John Entwistle of The Who, whose search for extra volume led Marshall to design the classic 100-watt valve amplifier. [18]
It is one of the largest tubes in its class and can handle significantly higher plate voltages than similar tubes, up to 800 volts. A KT88 push-pull pair in class AB1 fixed bias is capable of 100 watts of output with 2.5% total harmonic distortion or up to about 50W at low distortion in hi-fi applications.
Following a move to Bar Hill, Cambridge circa 1975, or just before, HH extended its range of sound reinforcement equipment to include models such as the MA100 Mixer Amplifier, a 100 watt, 5 channel PA amplifier 'head' with a switchable spring reverb. The IC100L, V-S Bass and the V-S Musician, a two-channel 100-watt guitar amplifier head with a ...
The Flexi-50 amplifier head was released in 2003, and made its debut at that year's Music Live event in the UK. It is a 50-watt, class-AB amplifier, meant to “create an idealized (Marshall) ‘Plexi’ tone". [20] As a “subtle homage” to the Plexi, the Flexi's faceplate is gold Plexiglas. [20]
The Memphis also marked the return of combo amplifiers to the Fryette line. The Class A, 2 channel Memphis Thirty 1x12 was the first amp in the new Memphis Series and features EL84 power tubes, 30 Watt & 18 Watt power modes & a unique removable hatch on the front panel allowing users to easily access and change pre-amp tubes.
The key to understanding this efficiency without churning the actual numbers is that we have a 400-watt-capable amplifier but with the efficiency of a 100-watt amplifier. This is because the waveforms of music contain long periods under 100 watts and contain only brief bursts of up to 400 watts – in other words, the losses at 400 watts are ...
The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, who were owned by Philips. [1] The EL34 has an octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between ...
