Audio Transformers datasheet and documents for PAM-OT-45-11R
Audio Transformers Overview
The PAM-OT-45-11R is an audio output transformer manufactured by Pacific Transformer, designed for chassis mounting in tube amplifier circuits. It features a primary impedance of 4.6kCT Ohms and a secondary impedance of 4 Ohms. The unit measures 4.030 inches in length and 3.200 inches in width (102.36mm x 81.28mm). This component serves as a direct replacement for specific vintage Fender Bassman amplifier models, ensuring proper impedance matching between vacuum tubes and speakers.
Audio Transformers Feature Summary
- Engineered for precise impedance transformation between high-impedance primary and low-impedance secondary circuits
- Constructed for durable chassis mounting in professional and vintage audio equipment
- Designed to replicate original specifications for accurate signal transfer in tube amplifiers
Audio Transformers Applications
- Fender Bassman amplifier restoration (Models: 6G6A, 6G6B, AA864, AA165, AB165, AC568, AA270, AA371)
- Vintage tube amplifier repair and maintenance
- Custom tube amplifier building requiring specific impedance ratios
Audio Transformers Procurement Notes
Verify the exact amplifier model number against the supported list before purchase. Confirm physical dimensions fit the existing chassis layout. Ensure the required primary and secondary impedance values match the circuit design. Check availability status as lead times may vary. Request official documentation if specific electrical testing data is required for quality assurance.
Audio Transformers Selection Notes
Select this transformer when replacing failed units in compatible Fender Bassman designs. Ensure the new unit matches the original 4.6kCT primary and 4 Ohm secondary specifications. Consider mechanical mounting requirements and spatial constraints within the amplifier enclosure. Verify compatibility with the specific tube configuration used in the target amplifier model.
Audio Transformers Part Context
This component belongs to Pacific Transformer's line of custom audio transformers, which includes output, power, and impedance-matching designs. The manufacturer specializes in vintage replication and custom builds for tube amps, pro audio, and broadcast applications. The PAM-OT series focuses on maintaining historical accuracy for classic amplifier circuits.
Audio Transformers Replacement Considerations
Direct substitute for specified Fender Bassman models. Verify pinout and mounting hole alignment. No alternative part numbers are publicly confirmed for this specific application.
