Bremer-Tully Discard Old Standards of Comparison
THREE WINNERS
B-T "A" Transformer Makes a Power-Six "Electric"
Here's a real answer to Distortion,—the B-T Audio Coupler.
B-T Speaker Coupler Guarantees Improved Tone, Increased Volume, and Saves Speaker's Life.
Six Years' Success Back These New Products
Bremer-Tully have released a new product which should create world-wide discussion.
The old idea of "Amplification Curves" as a basis for comparing audio transformers has been discarded. It never was anything more than a very secondary matter.
B-T have always maintained that the real problem was "Harmonic Distortion," — and —
Now they have proved it in the new B-T AUDIO COUPLER.
It is more than a transformer, — and better, — although no one ever produced a better transformer than BREMER-TULLY.
A constant Impedance Core, — an air-gap, — Tertiary Loading Coil, — and finest laminations, combine to produce QUALITY UNEQUALLED anywhere, regardless of size or price.
"Harmonic Distortion" has had practically no attention. — the attempts being to improve transformers by increased size, — cast cores, etc. You can readily appreciate that BREMER-TULLY could not release this product if it was not superior.
Type 3-31 is for First Stage; Type 2-22 for second stage or for all stages where three stages are used, — as in replacing Resistance Coupling. Bring your set up to date with a set. Price each, $6.00.
