Above, VSEL Conqueror serial number 2181, also on this page. Two things of note are revealed by the pictures. First, the serial number plate is still hand stamped. Second, the Celestion date codes - 12th and 13th May 1969 - provide a terminus post quem for the fitting out of the cab. The amp may have been produced at some point beforehand.

11 July - part 2

A short note on Vox Sound Equipment Ltd serial number plates.

The earliest plates, with numbers in the low 2000s, were generally hand-stamped - as below, the scuffed plate from Defiant no. 2032 and the rather better one from Supreme no. 2027:

At some point after the new-style VSEL plate had been introduced, certain models destined for Denmark were designated simply with a letter and number:

"C1" = Conqueror. One can see "Conqueror" faintly underneath and the wattage rating "60" instead of "96". The amp is currently in Copenhagen.

"C2" = Dynamic Bass. Amp sold recently on dba.dk.

Although it's hard to read, it looks as though the plate of a Defiant, also in Copenhagen, was adjusted to read "B1":

Original markings erased. Stamped "B1" just visible. The plate is VSEL version 1.

If there was indeed a logic to this system, then:

A1 = Supreme

A2 = Super Foundation Bass

B1 = Defiant

B2 = Foundation Bass

C1 = Conqueror

C2 = Dynamic Bass

12th October

Some details relating to Vox Sound Equipment Ltd (mid 1968 - late 1969) and Vox Sound Ltd (late 1969 - c. 1972) expanded on these pages: VSEL Supremes, VSL Supremes, late Defiants, late Foundation Basses, and late SFBs. Please forgive the repetitions.

The earliest runs of VSL amps were made at Erith - the "West Street" works. Among these were the last Conquerors. Production of the Conqueror ceased at the end of 1970.

1971: the move to the Birch-Stolec factory. It is sometimes said that this was at Hastings. In actual fact it was at St Leonard's-on-Sea nearby - on the Ponswood Industrial Estate - where a number of important companies were also based, Phillips being one. Twickenham Transformers, which had premises a stone's throw away, was contracted to make units for the newly relocated Vox works. The contract with Lemark ceased.

Below, pictures of the factory from the 1971 Vox catalogue.

11th October

What was the "prototypes" page has become the pre-production page. It became clear that most of the amps illustrated were not prototypes at all - ie. not scrappy work-in-progress experiments - but finished factory-made items, sent out to shops as demonstration or promotional amps. This is why they appear in the adverts. The intention was to market them more or less as they were. But as a result of feedback and/or further consideration Vox/Burndept obviously felt moved to change the design when the time came to put the range into full production.

It has become clear too that the whole process was not invented on the spot - it simply followed the general pattern adopted by Triumph Electronics for the Vox 7-series amps that had been issued a year earlier (1966) - prototyping and testing behind closed doors, then a small production run - amps sent round the country for promotion and demonstration in May/June 1966 - then a little bit of tweaking before full production. Further details will be given on the 7-series site.
