Electronic organ, several models of which were manufactured by Philips Gloeilampfabrieken in Eindhoven and Philips Electrical in Croydon between about 1964 and 1971; some models were made in Berlin and in Hasselt, Belgium. The organ was designed for domestic use, but it was also employed in small churches and for educational purposes; the models range from a four-octave, single-manual instrument to a special version designed for churches, with two manuals and a full pedalboard. At least one model incorporates a cassette tape recorder. The sounds are generated by 12 oscillators using frequency division. A switch on single-manual models enables the keyboard to be split to produce two contrasted timbres, or assigns limited chordal functions to the keys of the lowest major 10th of the range, in the manner of the chord buttons on an accordion.A.
