This is a vintage Variac variable transformer with a 115V input and adjustable output voltage ranging from 0V to approximately 130V, as indicated on the dial. It is designed for precise AC voltage control, making it ideal for applications such as audio equipment testing, tube amplifiers, and laboratory use. The unit appears to be in good cosmetic condition, with clear markings and a smooth adjustment dial. However, it has not been tested, so it is being sold as-is, with no returns accepted. Please examine the photos carefully and feel free to ask any questions before purchasing.
