  • Leaky power transformer, a problem? [with pics!] | The Gear Page

    For the most part transformers do not have anything to leak out. The material in them can not turn to liquid and ooze out (at least at any reasonable temperature. Heat it to the melting point of copper and it is a different story) There are exceptions such as very large power transformers that used liquid for cooling, but these were never used in guitar amplifiers.

  • Transformer types - Wikipedia

    A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to the loose coupling between its primary and the secondary windings.
