Where a six step amplifier, that is, where six amplifying tubes are connected together, or in cascade, the first three are usually coupled up with radio frequency transformers and the last three with audio frequency transformers. A radio frequency transformer is shown at B and costs $6 to $7. An Audio Frequency Transformer Amplifying Receiving Set.
All of these transformers operate on 110 volt, 60 cycle current and can be connected directly to the source of alternating current. The Wireless Key.
Soft iron cores are not used in oscillation inductance coils and oscillation transformers for the reason that the frequency of the current is so high the iron would not have time to magnetize and demagnetize and so would not help along the mutual induction to any appreciable extent. High-Frequency Currents.

Seaton nodded permission, and from the eyes and from the hands of the figure there leaped visible streams of force, which seized the transformers, coils and tubes, and reformed and reconnected them, under Seaton's bulging eyes, into an entirely different mechanism. "Oh, I see!" he gasped. "Say, what are you anyway?" "Pardon me; in my eagerness I became forgetful.

She could make you see the romance in condensers and transformers. She had the power that caused the reader to lose himself in the charm of magnetic poles, and ball bearings, and high-tension sparks. "Just dropped in to say good-by," said Jock, very casually. "Going to run up-state to see the Athena Company toilette specialties, you know. It ought to be a big account." "Athena?"
The fourth class were the inhabitants of the water: these were made out of the most entirely senseless and ignorant of all, whom the transformers did not think any longer worthy of pure respiration, because they possessed a soul which was made impure by all sorts of transgression; and instead of the subtle and pure medium of air, they gave them the deep and muddy sea to be their element of respiration; and hence arose the race of fishes and oysters, and other aquatic animals, which have received the most remote habitations as a punishment of their outlandish ignorance.
The ship was five diameters out from Darth, and he'd released it from the landing grid fields. He turned and saw Hoddan. "What the hell do you want?" he demanded sharply. "A few kilowatts," said Hoddan. The redhead's manner was not amiable. "Get outta here!" he barked. The transformers and snaky cables leading to relays outside all were clear as print to Hoddan.
Thornton, infected by his friend's excitement, leaned forward in his chair. "Yes nearly. If only my transformers hadn't melted! You see I got the idea from Savaroff, who noticed that the activity of radium and other elements wasn't constant, but varied with the degree of solar activity, reaching its maximum at the periods when the sun spots were most numerous.
