The equipment at the right was demonstrated at the 1953 APAE and BSRA Exhibitions.
The TL/12 amplifier is shown on the center-right of the black and white photo, with the new "Vari-Slope" pre-amplifier, which can be strapped together into a single units for portable use suitable for public address applications.
The Leak "VS-Radio-Tuner" is shown on the left of the black on white photo, and also below in simulated colour. It features Variable Selectivity (6kHz, 12kHz and 24kHz) allowing the user to choose wide-bandwidth giving higher quality audio signals, or if required restrict the bandwidth to reduce interference. Although not stated, the VS-Tuner is for AM radio use. It requires HT and LT feeds from an associated power amplifier, as it does not have its own power supply built in.
