This thing I got at a flea market. It must be very rare indeed. I have found out that the unit is from 1952. Of course it's vacuum tube. I replaced the drive belt and recapped the signal capacitors in the amp, thus greatly improving performance. I will later make a video showing the recording function and it in more detail. There, as I found on the Net, I found that there was another Dormiphone unit that used a record player. But this one is tape. I found that these machines were used in the past to play subliminal messages to people while sleeping, to help learn a language or remember something. I also heard that they were used in research in ESP and dream telepathy. The clock works on this and all those switch things around it are switches to turn the machine on and off at times in the night, just like those plug-in timers for turning lights on and off to keep away robbers. Although I have the original microphone to this, it is dead unfortunately. I have since put a new crystal element into the microphone.
