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.
