A transformer is an electrical device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. There are many different types of transformers, but the two most common are power supply transformers and
free energy transformers.
A power supply transformer takes AC input voltage and transforms it into a specific output voltage, which is necessary to run electronic devices. A free energy transformer, on the other hand, takes in low-voltage AC input and outputs high-voltage AC output. This type of transformer can be used to create free energy devices such as motors and generators.
There are many differences between power supply transformers and free energy transformers. The most obvious difference is that power supply transformers output a specific voltage, while free energy transformers output a range of voltages.

This amplifier is based on the classic single-ended, iron-core 2A3 lamp tube. The electrical transformer provides the high voltage required by the 2A3 tube, and also shapes the audio signal to provide the desired sound profile. This amplifier is perfect for anyone looking for a classic sound profile with excellent performance.
