The VT2 is basically a V2 with changed tuner head. The V2 used 3 x EF80 as RF amp, Mixer and Local oscillator. It was only Band I. Some Band II VHF-FM radio sets did use 2 x EF80 or even an EF80 Preamp on ECC85. But really the EF80 is poor over 100MHz (Up till about 1970 there was no UK VHF-FM above 100MHz). The PCC84 & PCF80 allowed operation up to 220MHz (later TV sets would use up to 275MHz for VHF).
Though released in 1954, the VT2 model was ready for start of ITV in 1955. In 1955 there was also the first Set-top boxes, converters to add ITV (Band III) to BBC only (Band I) TV sets. Thus 2015 will be the 60th Anniversary of the Setbox converter which had a resurgence with final Analogue Switch Off on October 2012. Like later models close to 1962 (Start of BBC2 625 lines on UHF and 625 lines VHF 31st December 1961) which had options for 625 lines or UHF tuners or both some 1950s models had internal adaptor kits etc.
