  • ■See primary wiring information under resources.
  • ■Bias Tap: 50 VAC tap from high voltage secondary C.T. (except part number 379WX - uses a separate 60VAC 0.2 Amp winding).
  • ■Highpot tested: 2,000 VAC
  • ■Faraday Copper Primary Shield: Our 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 our entire 200 Series range of units PLUS 2 models designed specifically for 300B tubes (Part Number 300BX ) and 2A3 tubes (Part Number 302AX ).
  • ■Finish: Black powder paint to match our 1650 series of output transformers
  • ■Units can be run full wave bridge or full wave C.T.
  • ■Conservative designs - CSA certified (209651).
  • ■For a more economical, open frame, universal primary - check out our 260 Series .
  • ■For that "high end" look & feel check out our potted versions - the 300P Series .
