The Vox AC10C1 debuted in May 2015, fifty years to the month after the original Vox AC-10 amplifier last appeared in a Jennings Musical Instruments (JMI) Vox price list in 1965.
The Original JMI Vox AC-10 (1959 - 1965)
I
nitially introduced in 1959, the all tube JMI AC-10 bridged the gap between the student grade AC-4 and the professional level AC-15. The JMI AC-10 featured two channels, four inputs, tremolo, a tone cut control and a 10 watt power amp section driving a single 10" Elac or Goodmans speaker. The six tube AC-10 circuit included one each EF86, ECF 82 and ECC83 preamp tubes, two EL84 power tubes and an EZ81 rectifier tube.
Like its bigger brother, the AC-15, the AC-10 power amplifier was powered by two EL84 power tubes in a Class A, cathode biased, no negative feedback amp circuit. A close comparison of the AC-10 schematic (OS/008) and AC15 schematic (OA/031) reveals that both models have vitually identical electronic components, voltages and circuitry in their power amps.
The 1961 JMI Vox catalog suggested the AC-10 was ideal "for the smaller group."
| The earliest version of the single speaker AC-10 arrived in 1959 with a TV front cabinet covered in tweed vinyl (see photo at right). In 1961 the cabinet was redesigned to incorporate the classic Vox "split front" speaker panel. AC-10 amps built in 1961 and 1962 were covered in fawn vinyl with a transition to black vinyl in 1963. AC-10 amps built in 1964 and 1965 were offered exclusively with black vinyl. |

The Vox AC10C1 (2015)
The Vox AC10C1 joined the
Vox AC4C1,
AC15C1 and
AC30C2 as part of the "Classic Series" of guitar amplifiers.
Design - The AC10C1 is a 10 watt, single channel amplifier with one input. The JMI Vox AC-10 was a dual channel amp with four inputs.
Tube Complement - The AC10C1 employs two ECC83 preamp tubes and two EL84 output tubes.
Gain and Volume Controls - Unlike the original AC-10, the Vox AC10C1 has both gain and volume controls. This enables the preamp to be overdriven while keeping the total level of the amp in check.
"Top Boost" Tone Circuit - While the original JMI Vox AC-15 included a simple, passive treble cut tone control, the Vox AC10C1 features the "Top Boost" active tone control circuit with separate bass and treble controls. The "Top Boost" circuit was originally developed by Vox in 1960 to improve the treble response of the AC-30.
Reverb - Like the Vox Tony Bruno amplifier series and the NT50HG2 Vox Night Train head, the Vox AC10C1 includes a high quality digital reverb circuit.
Speaker - The Vox AC10C1 features a 10" VX10 speaker made for Vox by Celestion. The speaker is mounted in a closed back MDF enclosure covered in traditional Vox basket weave vinyl.
