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).
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 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.
Developed in response to requests from the Collins Collectors Association"this is a matching audio transformer for older equipment with 600 ohm audio outputdriving modern speakers. Or for "classic" high impedance speakers used with newer equipmentsimply swap primary for secondary (ie...4 or 8 ohm input and 600 ohms out). Key Features Isolation unit: (i.e.
