YOU are planning to build a radio receiver and you want to know what kind to make. Shall it be a onetube reflex, or a four-tube ultra-sensitive tuned and neutralized radio-frequency receiver using regeneration and push-pull amplification? The book which will satisfy the needs of every radio constructor, Radio Broadcast's Knock-Out Receivers, contains instructions on how to build these — in fact it tells how to make eight separate receivers.
There is no better group of receivers from which to pick the type to build than those contained in Radio Broadcast's Knock-Out Receivers because they have been designed by experts to fit the need of the broadcast listener. All of them can be built from standard parts.
Complete information is contained in the book (which has one hundred pages), for building these receivers, but no blue prints can be sold with it. Well known radio authors like Walter Van B. Roberts, Zeh Bouck, Kenneth Harkness, John B. Brennan,and others have written the descriptions. This book is now being printed and deliveries will be made at once. It will be sent to any address on receipt of $1.00.
