Product Features
  • Primary: Universal - 100, 110, 120, 200, 220, 230, 240 VAC 50/60 Hz.
    • Note: Units are designed to operate with BOTH primary windings engaged.
  • Bias Tap: 50 VAC from high voltage secondary C.T. (except Part number: 379WX - uses a separate 60VAC 0.2 Amp winding).
  • Hipot tested: 2,000 VAC.
  • Faraday Copper Primary Shield: The electrostatic shield reduces the capacitive coupling from the primary - greatly attenuating higher frequency current coupling to the secondaries (shield is internally grounded to the end bell.
  • Windings: Concentric wound for low stray field and low noise.
  • Models: This series is an upgrade from the entire 200 Series range of units PLUS 2 models designed specifically for 300B tubes (Part number: 300BK) and 2A3 tubes (Part number: 302AX).
  • Finish: Black powder paint to match the 1650P Series of output transformers.
  • Units can be run full wave bridge of full wave C.T.
  • Conservative designs - CSA certified (209651).
