Fender Bassman 5F6-A Tube Amps Circuit.
The Bassman was designed for the first mass-production electric bass, the Fender Precision Bass. It was introduced in 1952 and discontinued in 1983. Up to until 1954, the Bassman amps had only 1 speaker (circuit 5B6), but it was the four 10″ speaker combination that came to be one of the greatest and most sought after amplifiers in history. The original series of 4×10 Bassman amps included the 5D6 (1955), 5E6 (1955), 5E6-A (1955-1957), 5F6 (1957) and 5F6-A (1958-1960) circuits.
In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.
In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
