The 290EEAZ is a 290 Series power transformer listed in the Fender section of the ordering table for the 94 TWIN REISSUE. What sets it apart is its multi-voltage primary, rated 120/210/220/230/240V @ 50/60 Hz, which makes it useful for amps that travel or live on non-120V mains.
Its secondaries match the 120V-only 290EAZ: 365Vct @ 850 mA for the high-voltage supply, 27.5V @ 100 mA, and 6.3V @ 4A for heaters. The ordering table lists bobbin winding.
Hammond designed the 290 Series for drop-in replacement of original units, with parts made to look similar to the original factory transformers where possible and materials and design specs kept as close as possible to the original part to preserve the stock tone.
Because the primary offers five voltage taps, the same transformer can be wired for the local supply rather than stocking separate regional versions. Check the original transformer's ratings, the mains voltage where the amp will be used and the tap you intend to wire before installing.
The part page describes the 290EEAZ simply as a power transformer and publishes no shipping weight or dimensions for it. It is RoHS and REACH compliant, with UPC 623980184593 and UNSPSC 39121301. Amp model references are for reference only; confirm against your chassis before ordering.
