# audio.parts ## Posts - [Where Quality Meets Transformers](https://audio.parts/where-quality-meets-transformers/): Where Quality Meets Transformers In most conventionally manufactured transformers, electrical insulation within a winding section relies almost entirely on the enamel coating of the copper wire. Additional insulation—such as tape or film—is typically applied only between winding sections. Within each section, the copper wire is often wound in a semi-random manner. This means that two adjacent wires can experience significant voltage differences. The result? A higher risk of short circuits and inconsistent inter-winding capacitance from one transformer to another. Because the majority of transformers worldwide are built this way, the industry has long associated transformers with variability and reliability concerns. - [Grounding and Shielding](https://audio.parts/grounding-and-shielding/): Line Output One of the objectives of an output transformer is to give the output line a high and symmetrical impedance versus ground. This is obtained with transformer Faraday shield(s) or symmetrical winding arrangements. The symmetry is necessary to prevent mode transfer, i.e. common mode signals picked up by the output line creating differential mode signals (IRT test). The shield(s) also contributes to: Output signal balance (IEC test) Protection of the output stage from high line voltages caused by lightning Grounding:The line shield and the transformer shield / the transformer primary cold connection should be connected to the ground of - [Mixed feedback drive circuits for audio output transformers](https://audio.parts/mixed-feedback-drive-circuits-for-audio-output-transformers/): Adipiscing hac imperdiet id blandit varius scelerisque at sagittis libero dui dis volutpat vehicula mus sed ut.
