RADIO BROADCAST ADVERTISER
The Shielded Six is one of the highest types ot broadcast receivers. It embodies complete shielding of all radio frequency and detector circuits. The quality of reproduction is real — true to the ear.
Behind the Shielded Six is competent engineering. It is sensitive. Day in and day out it will get distance— on the speaker. It is selective. Local stations in the most crowded area separate completely — yet there are but two dials to tune. These features — its all metal chassis and panel, its ease of assembly and many others, put it in the small class of ultra-fine factory-built sets, priced at several times the Six's cost.
