Coils for the "Cathode"

HILE winding the coils for the "Cathode Super," it occurred to me to make a small alteration in the connections to the pins on the oscillator coil to avoid the possibility of 2 short-circuit if the formers are inadvertently placed in the wrong holders. The point is perhaps a trivial one, but ‘the alteration is easily carried out and tends to make the set more fool-proof. All that is necessary is to change the connection of the tap on the oscillator coils from pin 1 to pin 2 (Colvern formers). If the oscillator coil is then placed in the detector holder by mistake the H.T. is not shorted to earth.-
