All amps are individually made: "it's possible that no two Trainwreck amplifiers actually have the exact same circuit". They are usually equipped with three 12AX7 preamp tubes. [10] Fischer made three kinds of models: Express; two EL34 or two 6V6 output tubes. Two 12AX7 preamp tubes and one 12AX7 phase inverter. (Highest-gain amplifier in the ...
The company's flagship amp [3] is the BE-100, which was designed as a clone of a 1968 Marshall "Plexi" Super Lead circuit with a "variac," a tone inspired by high-gain 1980s sound of Van Halen. [2] The Dirty Shirley/Twin Sister is the company's take on the tone of 1960s and '70s British classic rock.
A genuine Signetics NE5532N in PDIP package, made in 1990, on a modem board A Texas Instruments SA5532A in SOIC package on an audio distribution amplifier board . The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.
This article lists manufacturers of bass amplifiers, loudspeakers, and other amplification-related items such as preamplifiers. The amplifiers and loudspeakers used to amplify bass instruments (e.g., the bass guitar, double bass and similar instruments) are distinct from other types of amplification systems due to the particular challenges associated with low-frequency sound reproduction.

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 ...
