Stancor P-6464 Transformer

Stancor P-6464 is a chassis-mount power transformer designed for vintage vacuum-tube equipment. It accepts a 117 VAC mains input on a single primary and provides a 6.3 VAC secondary (center-tapped) to power tube filaments, with a current rating of 10 A. The unit measures about 3.50 inches tall by 2.81 inches wide, making it compact enough for mid-century chassis installations while delivering reliable low-voltage power. This transformer is commonly used in classic tube radios and audio amplifiers where a robust 6.3 V filament supply is needed from a standard 117 V source, and it is aligned with Stancor gear that originally employed P-6464 parts. When installing, ensure your chassis has suitable mounting clearance and the correct pinout for the 117 V input and the 6.3 V output. The P-6464 sits in Stancor’s lineup of vintage power transformers, historically cataloged as a 6.3 V center-tapped secondary with a 117 V primary and a 10 A rating, offering a straightforward, isolated supply for filament currents in tube circuits.
