This paper proposes the method to synthesis vacuum-tube audio amplifiers that using the electronic DC transformers to replace the traditional audio-frequency output transformers usually used in the output stage of the amplifier. The proposed amplifiers can achieve the frequency response from DC-100kHz if the DC transformers operated at 400 kHz switching frequency and interleave technique are used. The principle of operation, DC model and various examples are given.
