Mardas gave the Beatles regular reports of his progress, but when they required their new studio in January 1969, during the Get Back project that became Let It Be, they discovered an unusable studio: no 72-track tape deck (Mardas had reduced it to 16 tracks), no soundproofing, no talkback (intercom) system, and not even a patch bay to run the wiring between the control room and the 16 speakers that Mardas had fixed haphazardly to the walls. The only new piece of sound equipment present was a crude mixing console which Mardas had built, which looked (in the words of Martin's assistant, Dave Harries) like "bits of wood and an old oscilloscope". The console was scrapped after just one session. Harrison said it was "chaos", and that they had to "rip it all out and start again," calling it "the biggest disaster of all time." Harrison's suspicions of Mardas' competence had been raised when he saw him wandering around in a white coat with a clipboard, and considered the possibility that Mardas had "just read the latest version of Science Weekly, and used its ideas". Mardas later stated that he had never been in the basement of Savile Row, as the studio equipment he was building was being tested in Apple Electronics, at Boston Place, Marylebone.
