The 1760E is a 15 watt push-pull output transformer for tube guitar amplifiers, listed for the Fender Deluxe 5E3 and Princeton and similar to Fender part number 50246. It is a drop in replacement for original units aimed at technicians and builders working on tweed-era Deluxe circuits.
It pairs an 8,500 ohm center-tapped primary with 4, 8 and 16 ohm secondaries and is bobbin wound. Typical frequency response is 70Hz to 15KHz (0/-1dB referenced at 1KHz) with distortion below 1% at 70Hz. DC resistance is 154.40 ohms (primary brown-red), 159.20 ohms (primary red-blue), 0.410 ohm (black-yellow), 0.540 ohm (black-green) and 0.830 ohm (black-white). Primary brown-blue inductance is 21.60H (129 K ohm) at 1.0 kHz, 1.0 V, and leakage inductance is 323.9mH. Dielectric strength is 1500VRMS and the temperature range is -40 to 105 degC.
Construction keeps materials and design specifications as close as possible to the original part to preserve the stock tone. The open style transformer has all leads at least 9 in long: brown, red (center tap) and blue on the primary; black (common), yellow (4 ohm), green (8 ohm) and white (16 ohm) on the secondary.
Drawing dimensions are A 3.250 in, B 2.085 in, C 1.995 in and D 2.813 in, with 0.187 x 0.300 in slots. Shipping weight is 1.2 lbs (0.54 kg). The manufacturer short description reads "OUTPUT12W TWEED DELUX SEC=8OHM". The 1760E is RoHS and REACH compliant.
Ideal For
- Replacing the output transformer in a Fender Deluxe 5E3
- Princeton amplifier repair
- 5E3-style tweed amp builds
- 15 W push-pull tube amps needing 4, 8 or 16 ohm outputs
