High Voltage (Plate) & Filament (300 Series) - Hammond Mfg.
Quality Products. Service Excellence.
High Voltage (Plate) & Filament
300 Series
Universal Primary & 50/60 Hz Operation
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.
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.
