Radiola III
INTRODUCTION
The RADIOLA III is a high grade regenerative radio receiv-
ing set especially designed for broadcasting reception.
It uses
two
WD-11 Radiotrons
which
are arranged to operate as a detector
and
audio amplifier.
Four antenna binding
posts are
provided
so
that
a choice of two types of tuning circuit may be had.
One is
a
sensitive single tuning circuit that has made an excellent reputa-
tion in the Radiola Senior, while the other is a more selective
circuit for use when interference is present.
The apparatus is
mounted below an attractive horizontal panel of durable molded
material and is enclosed in a solid mahogany case.
A flexible
