Fig. 59. We have hers a loop receiver with two stages of

tuned radio frequency amplification. This type of amplifier is very

efficient The coils L and L-1 will have the same values and may

be Honeycomb coils. However, 35 turns of wire on a 3 in. tube is

the approximate value for broadcast wave lengths.

Fig. 80. With thin combination It is possible to cover a coneiderable

range and obtaia fair volume. It consists of one stage

of tuned impedance radio frequency amplification and one stage of

audio frequency amplification, in conjunction with a single circuit

receiver. Cell L is approximately 35 tarns of wire on a 3 in. tube,

or a Honeycomb coil of a similar size.
