PAM-PT-50-50R is listed in the Power Transformers range at ChipApex. The manufacturer field lists Pacific Transformer. Its product description is Vox AC50 Power Transformer. Review the specifications below when checking this part for your BOM.
The PAM-PT-50-50R is a power transformer manufactured by Pacific Audio Magnetics, designed as a vintage replication for the Vox AC50 amplifier. It features chassis mounting with specific dimensional tolerances of ±0.063 inches and a reference height of 3.75 inches. The component supports primary voltages of 120V, 220V, and 240V, with secondary outputs including 720V at 70mA and 6.3V at 6A. This unit serves as a direct replacement for original equipment manufacturer parts, ensuring compatibility with classic tube amplifier circuits.
Verify the specific manufacturing date code and physical dimensions against the target amplifier chassis before purchase. Ensure the primary voltage configuration matches the local power supply requirements. Confirm that the secondary winding specifications align with the existing circuit board layout to guarantee proper integration and safe operation within the audio equipment.
Select this model exclusively for Vox AC50 applications due to its specialized winding ratios and form factor. Standard generic transformers may not provide the correct impedance matching or voltage levels required for optimal performance. Consider the physical size constraints when designing enclosures, as the chassis mount style requires adequate clearance for installation and heat dissipation during continuous operation.
Pacific Audio Magnetics specializes in custom and distribution transformers, producing components for audio and industrial applications. The PAM-PT series focuses on replicating historical transformer designs for the music industry. This specific part belongs to a line dedicated to maintaining the sonic characteristics of classic British amplifier brands through precise engineering and material selection.
This unit replaces OEM part numbers 73691 and 09-5401-0. Verify that the replacement matches the original electrical ratings to prevent damage to output tubes. Ensure the new transformer fits within the existing chassis without modification.
