  • Leak Transformer Parameters

    Notes from Leak Amplifier Owners: 1) Stereo 20 power transformers appear to have been revised during the production run. Early models had 300-0-300 volt HT secondaries, but this was revised to 280-0-280 V, possibly from a propensity for this transformer to overheat. The Leak circuits do not document this change. Comments from owners are welcome.

  • 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
