Hammond 1750B 10W 5,482Ω-to-8Ω Single-Ended Output Transformer

Best for

A schematic-verified single-ended Fender-origin repair or custom build requiring an exact 5,482-ohm primary, 8-ohm secondary, 10 W rating and the mechanical dimensions in Hammond's 1750B drawing.

Who should skip

Skip it for push-pull circuits, non-8-ohm speaker loads, applications whose tube/load-line target is not 5,482 ohms, power requirements above 10 W, unmatched chassis or mounting, or installation without qualified high-voltage service.

Watchouts

Tube amplifiers can retain lethal voltage after power is disconnected. A qualified technician must safely discharge capacitors and verify the circuit. The title's 5.48K is rounded; Hammond's exact primary specification is 5,482 ohms. No exact compatible Fender model, original part number or circuit revision is asserted.

Likely add-ons

• qualified tube-amplifier technician and high-voltage-safe service equipment
• application-appropriate mounting hardware; confirm inclusion and chassis fit
• single-ended circuit and 8-ohm speaker load matching the exact 5,482-ohm primary and 10 W rating

Verify before buying

• Does the exact amplifier schematic require a 5,482-ohm single-ended primary, 8-ohm secondary and 10 W rating?
• Do the output tube, operating point and speaker load match the transformer's electrical contract?
• Do the 2.375-inch drawing dimension, 0.187-inch mounting holes and minimum 9-inch leads match the chassis?
• Is a qualified technician equipped for lethal-voltage tube-amplifier service performing the installation?
