A number of former JMI executives and engineers continued to operate Vox from 1968 through 1969 while Royston was in receivership. As part of a settlement with Tom Jennings, the Jennings Musical Industries (JMI) name was dropped in favor of "Vox Sound Equipment Limited " or "VSEL." The name was eventually shortened to "Vox Sound Limited" or "VSL." Neither Tom Jennings or Dick Denney were involved in this enterprise.

The Vox VSEL era was short lived. In a little more than a year, VSEL itself slipped into bankruptcy, largely due to undercapitalization and the lack of market acceptance for their new Thomas Organ inspired solid state amplifiers.

VSEL continued to produce a number of hand wired AC-30 and AC-50 amplifiers during its brief existence. The AC-30 Top Boost amplifier shown on this page was produced during this era.

Perhaps the most obvious US influence on the 1969 VSEL AC-30 was the adoption of the US style horizontal Vox nameplate. Other US influences include black diamond Vox grill, cross braced speaker holes and the use of six slender air vents. Like Thomas amps, the rounded inside radius on the rear corners was eliminated. The "etched and filled" procedure used to make JMI AC-30 control panels was dropped in favor of a less costly (and less durable) silk screened process. Eight "two-pin" corners with a Vox logo were installed on the VSEL AC-30 (photo at right).

The cabinet was covered in traditional Vox basket weave vinyl with gold string accents. A silk screened serial plate, somewhat crude in appearance by JMI standards, was mounted to the upper back panel.

The chassis and hand wired circuitry of the VSEL AC-30 remained essentially unchanged from the original JMI design. The circuitry included five ECC83, one ECC82, four EL84 and one GZ34 tubes. The "Top Boost" controls were mounted on the control panel.

JMI typically used transformers sourced from Albion or Woden. VSEL replaced these with transformers from Lemark.
