28. portable radio that came my way had an open circuit primary winding in the output trans former For the reason of electrolysis and possibly some post war dodgy materials or parts should agree with tony Another bitey occurs in the Mullard 651A mantel radio that is claimed not to need an aerial wire although there is an aerial terminal The manufacturer claims that the 240 volt mains is used as an aerial True There is a radio fre quency capacitor 150pf connected between the aerial terminal and the Neutral black or blue wire of the 240 volt mains supply to the radio Should this capacitor fail there would be unspeakable damage done to the radio s circuitry and the listener as he used it as the 240 volts mains goes for an uncontrolled romp through the guts of the radio remove the capacitor and connect an aerial in the normal and safe way Look before you leap is a good addage for many of these old radios obtain the circuit and read it first Happy collecting and restoring FRED 12 Radiogram Issue 120 March 2012 13 New acquisition The iSing Gramophone A very rare gramophone has been added to the collection of club member Richard Rennie The machine is the iSing It is a precursor to the iPod and the iPhone iSing gramophones were made by the Marzipan Talking Ma chine Company in Kandi India in the period 1910 to 1915 The iSing has a case approximately 14 inches by 14 inches It is finished with imitation wood grain and i
