Stancor P-8688 Transformer

Stancor P-8688 is a power transformer that accepts a 100–115 VAC, 60 Hz mains input and provides an 18 VAC secondary capable of delivering up to 12 A. With an 18 VAC, 12 A output, the unit can supply up to 216 VA of secondary power (18 V × 12 A), which supports the low-voltage portion of equipment that requires a stable 18-volt supply while maintaining isolation from the mains. This model is part of Stancor's vintage line of transformers, representing North American mains designs used in classic gear. Identified by the P-8688 part number, it would be cataloged alongside other Stancor P-series transformers and is appropriate for projects needing a single 18 VAC winding with high current capacity. In practical terms, it serves as a dedicated 18-volt AC source for power-supply stages, test fixtures, or repair work involving vintage electronics where a reliable 18 VAC rail is required.
