Coming shortly, coverage of the "Vox Sound Limited" catalogue of late 1971. This was produced to accompany the Russell Hotel Trade Fair in August and encompasses the short-lived "Slave Master" range along with much else. Text throughout is in English, French, and German.
The loose-leaf format (with removable plastic spine) had previously been used by JMI, notably for its 1964 catalogue.

Thanks again to William, some great pics of the electronics of "Vox Sound Limited" Defiant serial number 2543 - extremely useful to have date codes at this point in production. The amp was probably ready for sale at some point in the third quarter of 1970.
16th November
Thanks to William, a couple of pics of a nice "Vox Sound Equipment Limited" Conqueror set, sold at one time by Joe O'Neill Limited of Glenamaddy. Interesting to see the preamp with its grey CCL capacitors, late 1967 date codes (for their manufacture). The latest visible component is a blue CCL electrolytic capacitor with the date code "6904" = 4th week of 1969. The order code for the CCLs - of all values - was "240". More to come.
13th November
Thanks to Steve, pictures of "Vox Sound Equipment Limited" PA50SS serial number 1157, a relatively early one with metal grilles across the vent openings. Plastic vents were introduced later in the production run.
At present, this is the earliest PA50SS to have come to light. The page on Vox solid state public address amps will be rearranged shortly.
PA50SS serial number 1157.
2nd November
Some updates to the page on Vox grey wah pedals. Thanks to Niels for pictures of serial number 5654.
Serial number 5654.
1st August
Just to note that the pre-production power section illustrated in the previous entry came in a Supreme formed from three separate elements - standard late JMI preamp; VSEL box with no serial number plate (none was ever fitted); and the pre-production power section.
The preamp has the latest JMI number that has so far emerged: number 2448. The sequence began at 1000. Treble preamps were common to the Virtuoso, Conqueror, Defiant, and Supreme.
It should be said, however, that following the collapse of JMI, a certain number of units were bought in by the new company "Vox Sound Equipment Limited" and given new control panels.
Treble Serial No. 02448.
