Build a B-T Counter phase Six
New Construction Plans Eliminate Chances of Error
A six tube receiver with three stages of radio frequency, — a set that gives distant reception with only a short indoor aerial and is the last word in selectivity, yet uses only two tuning dials.
Such a receiver is the new B-T "Counterphase"-Six, which a leading radio editor terms, "The only new circuit of the season."
You can build this master-set yourself. The B-T system of instructions makes it easy for the most inexperienced to construct a "Counterphase." B-T Kits contain the essential parts together with all radio frequency leads cut and ready to place in position. A series of progressive charts in nine-color combinations show exactly where each wire goes. Printed instructions take you through the whole job step by step. You can't go wrong,— never before has there been such an easy way to build a receiver. A set of these instructions is included in each kit.
You can also build a "Counterphase" with two or one stage of radio frequency for use with an outdoor antenna.
See your dealer about a "Counterphase." Ask him to show you the new B-T method of construction.
"The Best we Ever Tested—"
says a leading laboratory of the "Euphonic" Audio Transformer. Tone quality is the outstanding feature of this transformer. We have named it the "Euphonic" because it is "Pleasing to the Ear."
In addition to being a transformer of merit the "Euphonic" possesses an added mechanical feature that eliminates howling and distortion due to crossed or too close leads. Case and brackets are so designed that the "Euphonic" may be mounted in any desired position with the terminals always in place for correct wriing.
This feature is found only on B-T "Euphonies."
Condensers Built as only B-T Can Build
Never has there been a condenser that made the success with radio engineers, technical writers, experienced set builders,— the men who know that did the B-T "Lifetime" Condenser. Its mechanical and electrical superiority appealed to them from the first.
You can now secure this same quality in Straight Line Frequency. You can pay more for condensers but you can't buy as much. That's why we print on every carton, "If you don't find it better, send it back."
