LATER VOX DEFIANTS

Vox Sound Equipment Limited - 1968-1970

VOX SOUND EQUIPMENT LTD

1968-early 1970

The picture above is from the Vox Sound Equipment Ltd catalogue of early 1969. £235 is roughly equivalent to £3,550 in today's money.

"Vox Sound Equipment Limited" (VSEL) was set up in mid 1968, rising from the debris of JMI, which had begun to decline in late 1967. Its executives were former JMI men. For the background to the new company, .

Many of the amps initially sold by VSEL had actually been made during the last months of JMI. These were simply "rebranded" as Vox Sound Equipment Ltd, with new serial number plates, new control panels, and handsome stickers on the magnet covers of the speakers. Production of new items continued at the West Street works (the Burndept factory) in Erith.

New chassis and preamp sections were not stamped with serial numbers as JMI units had been.

New supply lines were set up for some components - Mullard/Phillips mustard capacitors for instance come in and yellow Lemcos go out.

Transformers were units with bare metal shrouds supplied by "Twickenham Transformers" (and marked "TT"), a company owned by "Stolec" = "Stow Electronics" and based on the Ponswood Industrial Estate (Windmill Road, St Leonard's-on-Sea, Sussex, TN38 9BY). Later, in the VSL period (from mid 1970) they were supplied by "Lemark", based in Haywards Heath and owned by "Birch-Stolec", which owned "Vox Sound Limited".

Serial numbers of VSEL Defiants begin at 2000, as do later amps throughout the solid state range.

Certain models destined for Denmark were designated simply with a letter and number:

  • A1 = Supreme

    A2 = Super Foundation Bass

    B1 = Defiant

    B2 = Foundation Bass

    C1 = Conqueror

    C2 = Dynamic Bass

The schematic for the preamp is at first OS/136, the power amp OS/134. By 1970 the sheet for the preamp is OS/184. The new circuit without standby was introduced at the very end of the VSEL period (late 1969) - certainly by the time serial number 2278 had been produced - see below.

Below, a register of surviving amps. If anyone knows of Defiants that have not yet been included on this page, do let me know.

Early Defiants (mostly issued by JMI in 1967) are registered , and . Later amps sold by "Vox Sound Limited" from mid 1970 to late 1972 .

Note the use of a "1" for the "I" of Defiant. This amp has a non-standard top control panel fascia, either an original "prototype/stand-in", or a later replacement. There are no signs of anything pre-existing underneath, however. Note the general resemblance to the panel from a prototype AC30, above. The preamp has a JMI inspection stamp, so this is evidently stock taken over by VSEL. The knobs are modern replacements, but for one original without its skirt. Pictures of the box and the power amp, both in poor condition, to follow.

A nice rig missing just its cabinet mounting hardware and footswitch. Note the light grey hard rubber wheels on the side stands. These are a Vox Sound Equipment Ltd thing. Earlier JMI side stands have larger black casters - late in the run metal hoods appear for a short time.

Produced for the Danish market, and presumably shipped for sale to one of Alfred Christensen's shops. Note, as in the case of another Defiant in Denmark further up this page, the designation "B1". Speaker cab no. 262 with its original Goodmans ceramics and handsome speaker labels. Thanks to Morten for the pics.

Serial number unknown - currently in France

Still two lamps on the front of the preamp, but the box has a plain tolex back and plastic vents on top. Probably a transitional amp (transitional between VSEL and VSL). Note the coloured counters on the knobs. The cab, which has similar proportions to 7120, is a specially-made 2x12".

Serial number unknown

Either late Vox Sound Equipment Ltd - note the decals on the speakers - or early Vox Sound Ltd. A nice rig, the pictures showing the extent of the tilt-back.

No standby circuit

A single indicator lamp on the front of the amp

At this point the MRB changes to a six position effect (rather than three). For an outline of the circuit, see this page.
