Advert from the Melody Maker, April 10th 1971

The V100 - Vox Sound Limited's move to introduce a 100W valve "concert" amp, perhaps too late in an already crowded marketplace. The recommended cab or cabs will presumably have been a Supreme 4x12" (midax horns had been dispensed with by 1971), a multi-link 4x12", or a 2x15" + 2x12", though nothing is said in the brochures and adverts.

Had a "name" artist or group taken a V100 or two up, VSL might have capitalised. As it turned out, probably fewer than two hundred were produced - a pity, as the amp is capable of producing a good sound. Pictures of anyone using V100s on stage in the 1970s have yet to emerge.

Nor a price-list to show how much the amp cost.

As can be seen from the flyer above and the images of amps below, the box was effectively a standard solid state amp box slightly reworked.

The power section of these amps was based in part on the last iteration of the Vox AC100 - zener diodes to provide the bias voltage; doubled-up filter capacitors to increase reliability; and still the brimistor.

For reference, the last schematic of the AC100, re-drawn in VSEL days (4th December 1969), which shows the design was very much alive even if the AC100 itself was out of production:

To the left of V2, however, the Vox V100 is different, having only two preamp valves (two ECC83s).
