With a mono cassette head in the panel and a NAB equalised ampli er circuit, Magnetophon is a cassette player without the transport mechanism. Try rubbing old cassette tapes on the panel, or attach a head on a wire to recreate Nam June Paik’s Random Access or Laurie Anderson's Tape Bow Violin.

- C7 is NOT required but a space is left on the board in case you have any oscillation in the first op amp stage.
- *Electo caps should be short - 7mm tall - to fit between the boards. Otherwise, you can mount them on the back if you are careful of polarity.
- May 2016: Rev 1 (= Proto 2 with silkscreen tweaks) should be good to build.
- Proto 2 works well.
- Proto 2 designed and sent to fab
- Proto 1 used for 4 days straight at SuperBooth
- Proto 1 built, needed extra capactitor to kill huge ultrasonic oscillation
- Not verified
- January 2016 Prototype sent for manufacture
- October 2015 Designed
Named after the AEG Magnetophon, the first commercial tape recorder, revealed at the 1935 Radio Fair in Berlin.
