PAM-C-4-13R

Fixed Inductors Overview

The PAM-C-4-13R is a fixed wirewound inductor manufactured by Pacific Transformer, designed as a vintage replica component for audio applications. It features an inductance of 4 Henrys with a maximum current rating of 50 mA and a DC resistance of 150 Ohms. The unit is unshielded and utilizes a nonstandard chassis mount configuration. This component serves as a direct replacement for specific Fender OEM parts, including part numbers 125C3A and 022707, ensuring compatibility with classic amplifier designs from the 1964-1967 era.

Fixed Inductors Feature Summary

• Vintage replica design matching 1964-1967 era specifications
• Unshielded wirewound construction for authentic signal characteristics
• Chassis mount form factor for direct equipment integration

Fixed Inductors Applications

• Fender Brownface amplifier restoration
• Vintage audio equipment maintenance
• Classic tube amplifier circuit repair

Fixed Inductors Procurement Notes

Verify exact physical dimensions against target equipment before purchase, as the nonstandard chassis mount may require specific mounting hardware or clearance adjustments. Confirm that the 50 mA current rating meets the circuit requirements, as alternative versions exist with higher current capacities. Ensure the unshielded nature aligns with the noise tolerance of the specific amplifier topology being serviced.

Fixed Inductors Selection Notes

Select this component when restoring amplifiers requiring original-style magnetic components with 4H inductance and low current handling. Compare against the PAM-C-4-10R if higher current capacity (90 mA) is needed, noting the difference in DC resistance. This model is specifically engineered for historical accuracy rather than modern high-efficiency standards, making it suitable for purist restorations.

Fixed Inductors Part Context

Pacific Transformer produces custom magnetics under the Pacific Audio brand, focusing on vintage replica components for guitar amplifiers. The PAM-C-4-13R belongs to a series of chokes designed to replace obsolete factory parts. These components are built in Anaheim, California, utilizing ISO 9001 certified processes to maintain consistency with historical electrical and physical specifications.

Fixed Inductors Replacement Considerations

This part replaces Fender OEM numbers 125C3A and 022707. Verify compatibility with the specific amplifier model, as other Pacific models like the PAM-C-4-10R offer different current ratings.
