  • Iso Transformer -- Osborne Transformer

    Iso Transformer Overview. Osborne’s iso transformer designs are used to step-up, step-down and isolate voltages. Isolation may be used to help provide a degree of secondary-side immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the primary-side system.

  • 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.

  • Liquid-Filled (Glycerin- or Silicone-Filled) Gauges - WIKA USA

    Liquid Filled vs. Traditional GaugesWhy Liquid filled?Liquid-Filled Gauges from WikaThe primary reason for gauge failure is vibration. In traditional dry gauges, delicate links, pivots, and pinions are prone to damage from vibration, leading to inconsistent performance. In a liquid-filled gauge, the fluid fill effectively dampens system pulsation, making the gauge pointer easier to read.Likewise, humidity and moisture pose problems for dry gauges. Condensation can make a gauge difficult to read or, in some cases, can cause failure due to icing. Liquid-filled gauges, though,...
