What happens out on the "skirmish line"?
When your set goes up to the front line to meet prospective buyers — does it have an outstanding strategic advantage over competition or is it just a "long, hard pull" for your dealers?
Radio receivers must satisfy two different types of buyers. One is the amateurs who not only know the difference between good and indifferent performance but who understand what causes the difference. They are also an important recommending factor in the final purchase of all receivers.
The other type is not technical-minded but regards a radio receiver simply as a musical instrument.

□ (For manufacturers) I am interested in engineering data regarding your transformers and condensers.
□ {For set builders) Please send circulars describing your apparatus and latest audio hook-ups. I inclose 10c to cover cost of mailing.
To both classes tone quality is all-important. When a dealer tells an amateur that your set has Sangamo Transformers in the "audio end" he knows that the tone will be right. He also has more confidence in your set all the way through because he knows that no manufacturer who uses Sangamo Transformers will jeopardize their performance by using inferior parts elsewhere in the set. When equipped with Sangamo Transformers, your set need only be demonstrated to sell those who judge by ear alone.
Sangamo "A" Line Transformers are built for the custom set maker or manufacturer who wants a "tone" advantage over competition. The cost is slightly higher but is more than offset by the increased salability of the receiver.
