• Notes

• The Ferrotune Four was a Radio & Hobbies adaptation of Kingsley Radio's KFT3.

  The Radio & Hobbies version is based around the Kingsley KFT3 Foundation Kit (consisting of the chassis, tuning mechanism & I.F. coils only) with some minor changes around the converter valve. This version uses a ECH35 converter instead of a 6J8G. The triode-hexode ECH35 here and the triode-heptode 6J8G of the other kit have different operating data and characteristics.

  Five pages of circuit & constructional details are given in a article in the November 1946 issue of Radio & Hobbies. The schematic was drawn by the late Neville Williams.
