Hammond 1750E 15W Fender Deluxe 5E3 and Princeton Output Transformer

Best for

Evidence-matched replacement or restoration work in a Fender Deluxe 5E3 or Princeton-family push-pull tube amplifier matching Hammond's cross-reference, 8,500-ohm centre-tapped primary, 8-ohm load, 15 W rating and mechanical drawing.

Who should skip

Skip it if the amplifier revision, circuit topology, primary or speaker impedance, power requirement, chassis dimensions, mounting centres or lead routing do not match the Hammond drawing and cross-reference, or if qualified high-voltage installation is unavailable.

Watchouts

Tube amplifiers can retain lethal voltage after power is disconnected. Installation must be performed by a qualified technician using safe capacitor-discharge and verification procedures. Verify circuit topology, impedance, load, power, mounting and leads. Hammond's abbreviated short description says 12 W, while its long description, attribute table, series row and drawing rate 1750E at 15 W; this catalog uses the convergent detailed 15 W rating.

Likely add-ons

• qualified tube-amplifier technician and high-voltage-safe service equipment
• application-appropriate mounting hardware; confirm inclusion and chassis fit
• a push-pull circuit and speaker load matching the 8,500-ohm centre-tapped primary and 8-ohm secondary

Verify before buying

• Does the exact amplifier revision cross-reference Fender 50246 or otherwise match the Hammond 1750E drawing?
• Does the circuit require an 8,500-ohm centre-tapped push-pull primary, 8-ohm secondary and 15 W output rating?
• Do the chassis, 2.813-inch drawing dimension, 0.187-inch mounting holes and minimum 9-inch lead routing fit without modification?
• Is a qualified technician equipped for lethal-voltage tube-amplifier service performing the installation?
