(26'45m.-527 m.)
It must be emphasised that the curves
shown are for an average receiver and are
drawn to give the listener some know-
ledge of the wavelengths covered by each
position
of
the tank condenser. In-
dividual receivers will vary somewhat,_
due to different valve and circuit capaci-
ties,
and the effect of
aerial load,
although minimised in this receiver, will
influence the wavelengths covered to a
small degree.
AS S.W. ADAPTOR.
This
receiver
provides an
efficient
alternative to the super -het type of short wave
converter.
Its output can easily be connected
to the pickup terminals of a broadcast receiver
by a 1-1 transformer.

ADDITION OF H.F. AMPLIFIER.
The performance of the All World Two
can at any time be extended by the use of the
H.F. amplifier unit described on page 34.
In this case the output of the amplifier should
be connected to end 1 of the grid coil in the
All World Two.
If a common battery supply
is used, note special remarks in H.F. amplifier
article, otherwise automatic G.B. of All World
Two will be shorted.
