Transformer - Hammond, High Voltage Universal Plate & Filament, Vertical mount
- 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 P-T379WX - uses a separate 60VAC 0.2 Amp winding).

- 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 P-T263-X range of units PLUS 2 models designed specifically for 300B tubes (Part Number P-T300BX) and 2A3 tubes (Part Number P-T302AX).
- Finish: Black powder paint to match our P-T1650X series of output transformers Units can be run full wave bridge or full wave C.T.
- Conservative designs - CSA certified (209651).
