• Notes
• The best selling valve radio in Great Britain. The radio was also available in a walnut coloured Bakelite cabinet at les cost; later models had an IF/ZF of 470 kHz. The three voltages have to be changed by opening a screw and to put the wire to the other screw. At the back is given 200-250 Volts.
  A commonProblemis: Volume doensn´t go to zero on a strong signal if Potentiometer is at the CCW stop. Remedy: a 330 picofarad capacitor between Grid and Kathode of the UBC41. Short leads are important, and perhaps replacement of the big 100k resistor to the grid by a smaller sized one of the same value. See also info below.
