Hammond Transformers Model 300BX (300 Series)

Classic Plate and Filament Transformer - 280 VA, 800V C.T. @ 288 ma, 50 VAC

This high voltage universal primary transformer is designed to operate with BOTH primary windings engaged. They feature a Faraday Copper Primary Shield – this 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). The unit is concentrically wound for low stray field and low noise and is specifically designed for 300B tubes.

 

Features:

  • Primary: Universal - 100, 110, 120, 200, 220,230, 240 VAC 50/60 Hz.
  • Units are designed to operate with BOTH primary windings engaged.
  • Bias Tap: 50 VAC tap from high voltage secondary C.T.
  • 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.
  • The 300 series is an upgrade from Hammonds entire 200 Series range of units.
  • 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 Hammond’s 260 Series.
