5751 is the designation for a low-voltage, low-noise avionics vacuum tube popular as a pre-amplification tube in guitar amplifiers. The 5751 is a modified version of the 12AX7 and, having a gain factor of 70-80 (as opposed to the 12AX7's 100), is used to "soften up a harsh modern amp". [1]

12AX7 is a miniature dual-triode 6AV6 vacuum tube with high voltage gain. Developed around 1946 by RCA engineers in Camden, New Jersey, under developmental number A-4522, it was released for public sale under the 12AX7 identifier on September 15, 1947.
The 6N2P,, also sometimes spelled in English "6H2Pi", is a miniature 9-pin dual triode vacuum tube manufactured in USSR, Russia and China with characteristics similar to the 12AX7. The most significant difference between the two is that 6N2P has its two filament elements connected in parallel, unlike the series filament connection of the 12AX7, and it is thus only possible to operate it from a 6.3 volt, 340 mA filament supply
The Vox AC30 is a guitar amplifier manufactured by Vox. It was introduced in 1958 to meet the growing demand for louder amplifiers.

The Fender Bronco was a guitar amplifier made by Fender. It was the first Silverface amplifier introduced in 1967 to sport the modern-looking "tailless" Fender amp decal, which became a standard feature on other Fender amplifiers in the early 1970s. The Bronco was a student amp to go with the matching Bronco guitar. Bronco amplifiers were shipped as a part of the Bronco "student" package offered during that time, which also included the matching Bronco guitar, introduced that same year. Some early Broncos used the early-mid 1960s "tailed" amp logo. The schematics and manuals listed the Bronco and the Vibro Champ as the same amp, except for the red letters and labels stamped on the control faceplate. The controls were also the same. It was discontinued in 1975.
