Golden Age Radio Research


Introduction to Golden Age Radio Research
We love listening to our Golden Age Radio recordings, but it's not quite the same experience if you can't listen to them over the sweet, deep, mellow tone that only a genuine tube-powered Radio supplies. The warm glow of a radio dial and the tubes behind them also contributes to the ambience.

We've collected over 100 Golden Age vintage Radios over the years and we've added this feature to share some of them with you.

As we add to our collection of fully restored Radios--and works in progress--from the Golden Age, we'll continue to add them here.

The Echophone model S-4 is a 6-tube AC-powered TRF receiver that tunes the standard broadcast band. It continued the company's pioneering line of compact "Bantam" sets that debuted a year or so earlier. They were among the very first such sets offered to the public, appearing in the marketplace before even the ubiquitous Philco 20, one of the most famous of all such radios. Compacts were so named because they combined loudspeaker and electronics into one table-top cabinet that was considerably smaller than the normal sets of the day.

The 1931 Echophone Bantams were smaller, lighter and less expensive than the Philco model 20, and although they were prominently advertised and appeared to have sold quite well, they never achieved the sales success of the model 20. In fact, by 1934 Echophone was out of business and its assets were acquired by Hallicrafters.

Echophone promoted the Bantam by describing it as "the new idea in radio". Here's a selection of extracts from 1930 newspaper advertising:

...built for the limited quarters and thrifty budgets of the modern home. ..the NEW idea in radio. Small as a clock, compact as a watch, portable as a lamp.

"It had to come.... NOW it is here... this amazing new radio...the Bantam Echophone....built for the limited quarters and thrifty budgets of the modern home... small as a mantel clock...portable as a reading lamp...a miniature in every essential - and yet a radio built so fine that it brings in distance with the glorious tone you would hear from a front row seat."

"You can move it with one hand wherever you go - and just plug it into any light socket wherever you are. Take it from sunroom to bedroom or bath... take it to the office or hospital room...take it travelling with you.."

"Full Screen-Grid circuit .. All Electric .. Rich Burled Walnut Cabinet"

Echophone was based in Chicago and in 1934 the Corporation was purchased by Bill Halligan, who used the assets to found the Hallicrafters Company. Hallicrafters went on to produce affordable home and HAM equipment right through to the late 50's, practically the end of the tube radio era.

Technical Details:

The S4's chassis used the latest screen grid tubes, the line-up being 24+24 (2 stages of RF amplification), 24 (2nd detector), 27 (1st af amp), 45 (2nd af triode amp) and 80 (rectifier).

Tuning is by means of a thumbwheel, with the dial scale graduated from 0 to 100. The lower knob on the front panel controls the volume, using a potentiometer located in the antenna circuit (there is no AVC). The on/off switch is at the rear of the chassis and as was the case with most early sets it is by itself; it would be a year or two before this function would be almost universally combined with either the volume or tone control. The set uses an electro-dynamic loudspeaker that was manufactured by Jensen.

There are three connectors at the rear of the chassis, one for ground, one for a "short antenna" and the third for a "long antenna". Curiously, the only difference between the two antenna inputs is that the "long" one inserts a 0.0001uF series capacitor. The idea behind this "short" and "long" differentiation is unclear.

1936 Air Castle Table-Top

Air Castle was the house brand for the famed Spiegel Catalogue from Chicago. They contracted like most of the other catalogue retailers, from any number of branded and contract makers. Clearly, this was a high-end set from a fine maker. The radio was originally a six-volt battery set that was a later conversion to AC.
