Good description. :-) Another option I’ve used is to pick a transformer with dual 120/120 vac primaries, and use one as the primary, and the other as a HV secondary.

It is the only area in a conventional power amplifier likely to give trouble in EMC emissions testing [3]. Even if the amplifier is built into a solidly grounded metal case, and the mains transformer ...

An analog amplifier works in analogous fashion, regulating the output stage devices (transistors) to release power from the amplifier’s power supply to the loudspeakers in a manner that exactly mimics ...

A non-PFC transformer based amplifier can only draw approximately 1000W of usable power. Ignoring the NEC & UL (consuming 15A), that number increases to approximately 1200W. Using your 315Wx7wpc ...

The power supply circuit, designed exclusively for the preamplifier, enables a stable power supply unaffected by fluctuations from power demanded by the power amplifier stage. An oversized toroidal ...

Look under the hood of a high-end amp or pricey A/V receiver and you see a humongous power transformer. Powerful amps need big transformers to pull a lot of power from the wall outlet, and high ...

Figure 1 A simple amplifier circuit suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Advertisement The circuit is versatile; its gain can be varied ...
