I used to modify dual standard receivers to work on 'wired distribution' as it was called in London. It was only a matter of keeping the VHF oscillator running when switched to BBC2/625.
Receivers did not require a UHF tuner but needed to be fully dual standard of course.
To be honest I absolutely hated it! It was usually found linked in to older 405 line VHF communal aerial systems in local authority flats and was either grainy, covered in patterning, mushy sound, horrible or just completely unwatchable, probably due to lack of maintenance. I think the translator/amplifier cabinets were valve units manufactured by TELANG' [?] The channel used for BBC2 was band 1 channel 5 in London and the South East.
Luckily at that time and for a number of years there was little of interest on BBC2 so the terrible pictures were largely not viewed by Mr Average. John.
