Hammond
"Classic" 300 series, power transformers



Due to the large number of Hammond model numbers it is not possible to keep all items in stock. We have the types 300BX and 302AX on the shelf but otherwise we order them as we get orders. We can order any of the Classic 300 or 300P transformers for you. Let us know the Hammond model number and we will quote you a price.

Hammond "Classic" 300 series, power transformers

Key Features:

• Primary: Universal - 100, 110, 120, 200, 220, 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.
• 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.
• This series is an upgrade from the "200" SERIES range of units
• 2 models designed specifically for 300B tubes (300BX) and 2A3 tubes (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).
