Perceived fidelity (quality) of audio reproduction is a hardly quantifiable, subjective measure that should be left to each individual listener's taste. Apart from audio fidelity, circlotron OTL have certain benefits versus asymmetrical OTLs (i.e. Futterman amplifier) and conventional, transformer-coupled amplifiers: Scalability.
The primary winding of a modulation transformer is fed by an audio amplifier that has about 1/2 of the rated input power of the transmitter's final amplifier stage. The secondary winding is in series with the power supply of that final radio-frequency amplifier stage, thereby allowing the audio signal to lower and raise the instantaneous DC ...
The other channel was not encoded and simply passed thru, via another audio transformer. This is how the effect could be encoded without slightly delaying one channel, which would have only provided close enough to 90 degree phase shift within less than an octave and somewhere between 0 and 180 degrees of phase shift is approached at the ...
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave.In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal.
In telecommunications, a repeating coil is a voice-frequency transformer characterized by a closed magnetic core, a pair of identical balanced primary windings, a pair of identical but not necessarily balanced secondary (drop) windings, and low transmission loss at voice frequencies.

In a step-up transformer, conversely, the load is attached across the full winding while the source is connected to a tap across a portion of the winding. For a step-up transformer, the subscripts in the above equations are reversed where, in this situation, N 2 {\displaystyle N_{2}} and V 2 {\displaystyle V_{2}} are greater than N 1 ...
In a horn loudspeaker, the term acoustic transformer or acoustical transformer may refer to either of two components: Horn (acoustic) , which attaches to the compression driver unit Phase plug , a component within the compression driver, the interface between the diaphragm and the horn
