FOR YOUR CONDERATION IS A. WEIGHT: 10 LBS 8 OZ. BENCH TESTED WITH MULTIMETER. CONTINUITY CHECKS OUT ACROSS ALL WINDINGS AND PRIMARY/SECONDARY VOLTAGES READ STRONG AND STABLE UNDER NO-LOAD TESTING. ALL LEADS IN GREAT SHAPE. SOME SCRATCHES ON CASING AS PICTURED. Built to power large commercial/theater tube equipment or massive multi-channel broadcast setups. To put it into perspective, a standard vintage guitar amplifier or hi-fi stereo amplifier usually only requires a 6.3V tap rated between 2A and 5A. A transformer pulling 15.5A + 2.5A is massive “industrial-grade iron” designed to light up the filaments of an entire rack of power tubes simultaneously. It was used to supply heater current for. Large Theater & Cinema Amplifiers: Legacy Altec/Western Electric style multi-tube sound systems designed for movie theaters (where multiple large power tubes like 807s, 6L6s, or KT88s ran concurrently). Broadcast/Radio Transmitter Gear: Station modulation equipment and multi-stage studio amplifiers. Massive Industrial Power Supplies: Centralized laboratory or theater sound system rack power bays. WILL BE PACKAGED WITH EXTREME CARE TO SURVIVE TRANSIT. ANY QUESTIONS, PLEASE ASK.

Rare, vintage 1950s matched heavy-duty power supply component set manufactured by Union Switch & Signal. This matched trio was carefully removed together from a highly specialized railroad system’s 300V regulated power supply chassis used in railroad control tower operations. This industrial-grade iron is incredibly over-engineered, making it a premium choice for high-end custom tube amplifier builders, audiophile DIY hi-fi projects, or vintage radio restorations. Why this set is ideal for Tube Amp Builders: Continuous Duty Iron: Built to zero-compromise railroad safety standards for 24/7/365 operation without overheating. Vintage Steel Core: 1950s laminations provide excellent magnetic properties and the coveted harmonic compression/”sag” that modern transformers cannot mimic. Ultra-Quiet DC Filtering: The matched L1 and L2 choke coils provide a massive advantage for smoothing out high-voltage ripple, delivering a dead-silent noise floor for sensitive audio circuits. Included in this set:(1). Main Power Transformer: Style HT / Volts: 115 / Cyc: 50/100(2) Matched Filter Choke Coils: L1 and L2 inductors matching the power transformer chassis requirements. All components feature the original, intact Union Switch & Signal identification tags complete with factory serial numbers. Physical Condition: Excellent vintage condition. The iron cores, heavy frames, and original wiring leads are fully intact.
