Vox Sound Ltd - mid 1970-1972

Advert from Melody Maker, December 1970.

In late 1969, Vox Sound Equipment Ltd became Vox Sound Ltd and soon filed for bankruptcy, being saved by Corinthian Securities, which sold the business on to Birch-Stolec in 1970. The first Vox Sound Ltd Super Foundation Bass amps were made at the West Street factory in Erith (late 1969 to early 1971).

In 1971 operations moved to the Birch-Stolec factory on the Ponswood Industrical Estate at St Leonard's-on-Sea (a mile or so from Hastings).

TRANSFORMERS: in mid 1970, "Twickenham Transformers", which had, under George Stow's direction, supplied "Vox Sound Equipment Limited" - "Twickenham" was from 1967 a member of the "Stolec" Group controlled by Stow - became "Lemark Electronics". Production continued at the Haywards Heath factory. Occasionally the correspondence address is given as the Ponswood Industrial Estate (Windmill Road, St Leonard's-on-Sea, Sussex, TN38 9BY), the address of the "Birch-Stolec" group, which had taken over the production of Vox equipment in mid 1971.

Much as VSEL inherited older JMI stock, VSL inherited a certain amount of Vox Sound Equipment Ltd stock. Early amps often have VSEL on their control panels, but VSL serial number plates.

Vox Sound Ltd struggled bravely with the business of selling the solid state amps, but the market became increasingly tough. Super Foundation Basses remained in production until 1972.

Below, a growing register of surviving amps. If anyone knows of any VSL Super Foundation Basses that have not yet been included, .

The clearest external indication of a Vox Sound Ltd amp, should its number plate and control panel not be visible, is the silver string around its box.

A nice late SFB amp with a JMI 1x18" cab and stand. The cab and stand probably belong with serial number 1229 on the previous page.

A great SFB, the cab complete with its wheels and chrome amp support. Note that the speakers have "Vox Sound Equipment Limited" labels. The cab's logo is of the horizonatal type normally used on amplifiers - its designation "STF Bass" = "Super Twin Foundation Bass".

A nice rig with original chrome stand.

The speaker cab is a good deal earlier - JMI, therefore late 1967 or early 1968 ("Solid State" in the logo).
