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.
