  • Remarques
  • Short wave model; also available as long and short wave model. Incorporates the Mullard, R.I. and Varley Interdyne valve.
    By means of two separate anodes, a double grid, connected with symmetrical primary and neutralising windings, effective stabilising is produced without the use of auxiliary apparatus. Two HF stages are employed, the three transformers being enclosed in the compartments of a copper screening box. A wave range of 200-600 metres is obtained with adjustable aerial tappings. The valve detector is followed by two LF stages employing a combination of both resistance-capacity and transformer coupling. Tuning is effected by a single knob operating a three-section condenser arranged laterally behind the panel so that each condenser is closely associated with its transformer winding.
