Dating vox ac30 amps
British big band guitarist Dick Denney is credited as the godfather of the Vox AC30, along with engineer Derek Underdown.
Denney began work on the earliest version (with a single speaker) in 1959.
The roll call includes Birch-Stolec Industries (1970) Dallas Arbiter (1973), and Rose Morris (1978).
The company that introduced Vox was known as Jennings Musical Instruments, or JMI, headquartered in Dartford (the hometown of Keith Richards, mates).Here’s a little bit of both: Early AC30s were fitted with alnico magnet Celestion speakers.The tubes in a Vox consisted of EL84s in the output stage and 12AX7s in the pre-amp stage.Of course, Vox is still around today—and still vital.It’s been owned by Korg electronics since the early 1990s, with the manufacture of amps now taking place in China.
Instead, RM came out with a “Silver Jubilee” version in 1985 that trimmed back the gain in the preamp stage—a workaround for the cheap tubes available at the time.
