I’d guess that that was exactly what Hacker intended – a radio receiver for those who wanted to listen to programme content. Hacker also noted that it could be used as a tuner, feeding a hi-fi system, or in conjunction with a hi-fi speaker. At the time, Wharfedale and probably others were promoting the use of some of their hi-fi speakers for use in conjunction with better quality FM radio receivers. Those additional applications suggested by Hacker tended to preclude the use of equalization to create an initially more impressive – but ultimately probably more fatiguing - sound. Back in the day, a “quick and dirty” test would have been to tune into a relatively uncompressed FM broadcast and wait for a male voice spoken-word item. That would show up any “unnatural” equalization or problems in the bass. (Voices with rounded vowels seem to work better for this test, as does speaking at a not-too-fast speed, say 160 wpm.)
To some extent the Mayflower may have been a continuation of what the Hacker Bros. had been doing in their Dynatron era, before the latter company became but a faint Ekco of its former self. The Dynatron post-WWII integrated radio receivers had been of the console form, running through various iterations of the AM-only Merlin to the final R1712, then to the FM-only Ether Minstrel RV12. This had used the FM2 switched FM tuner, which was adopted by the BBC as the basis for its RC5/1A and RC5/1B rebroadcast and monitoring receivers. It was also used in the BBC HR/17A and HR/18A monitoring receivers.
By the early 1960s, console radio receivers may have been perceived as passé, so a table model was indicated, hence the Mayflower. Its ability to drive even large hi-fi speakers meant that anyone who wanted to recapture what the RV12 could do could get there by adding a suitable external speaker system.
