Decoding the Hammond 125ese Datasheet A Guide to Key Specifications

The Hammond 125ese Datasheet offers crucial information about the transformer’s electrical characteristics, physical dimensions, and connection diagrams. Understanding this information is key to selecting the right transformer for your project or ensuring a proper replacement in an existing amplifier. The datasheet ensures proper function of the entire amp circuit, and is vital for safety. The document details the primary and secondary impedances, which are critical for matching the output tubes to the speaker load. These impedance ratios are fundamental in amplifier design, impacting power output, distortion, and overall sound quality. The datasheet also specifies the transformer’s power handling capability, typically expressed in watts. Exceeding this limit can lead to transformer saturation, overheating, and potential failure. Knowing the power rating is essential for ensuring the transformer can handle the demands of the amplifier circuit. Here is a quick list of what you might find:

• Primary Impedance: Typically listed in ohms (e.g., 5000 ohms, 8000 ohms)
• Secondary Impedance: Usually given for various speaker loads (e.g., 4 ohms, 8 ohms, 16 ohms)
• Power Rating: Specifies the maximum power the transformer can handle (e.g., 15 watts, 25 watts)
• Frequency Response: Indicates the range of frequencies the transformer can accurately reproduce
• Physical Dimensions: Provides measurements for mounting and enclosure design

Furthermore, the Hammond 125ese Datasheet includes a schematic showing the wiring connections for the primary and secondary windings. This diagram is indispensable for correctly wiring the transformer into the amplifier circuit, preventing potential damage or improper operation.
