1、PAGE 8-A RADIOLA VII & VII -B Radiola VII is a new type of radio receiver, designed for use with Radiotron 1.:V199, which operates entirely from dry cells. Electrically, it consists of a highly selective 2 -circuit tuner and a 5 -tube detector -amplifier, self-contained and ready to connect to anten

2、na and ground (or to a loop antenna), and a loud speaker. The design is such that all batteries are contained within the cabinet. Radiola VII -B is a complete receiving unit comprising a set withitsbatteries and loud speaker mounted within an attractive cabinet. Electrically, Radiola VII -B consists

3、 of a highly selective two circuit tuner, with detector and radio -audio amplifier, using five UV -199 Radiotrons.These tubes are dry -cell operated and all neces- sary A, B and C batteries are contained within the cabinet, and connected to the receiver by a multi -conductor cable. The wave -length

4、range of the Radiola VII -B covers thebroad- casting band of 220 to 550 meters and through the useof specially designed radio frequency transformers practically equal sensitivity is secured over the entire wave -length band.
