The 291BEX is a 290 Series tube guitar amplifier power transformer described as a replacement for Fender guitar amps, with the amp model listed as GENERIC. It has a 240V @ 50/60 Hz primary and is intended for technicians who need these ratings on 240V mains.
The high voltage secondary is 660Vct @ 138 mA (Secondary 1), with a 50V bias winding (Secondary 2), 6.3V @ 3A (Secondary 3) and 5V @ 3A (Secondary 4). The short description reads 325-0-325,5V@3A, 6.3VCT@3A.
Like every 290 Series part, it was designed for drop in replacement of the original unit, physically designed to look similar to the original factory unit where possible, and built with materials and design specs kept as close as possible to the original part to preserve the stock tone.
Shipping weight is 5.32 lbs (2.41 kg). The 291BEX is RoHS and REACH compliant, with UPC 623980252568 and UNSPSC 39121301. The 120V @ 60 Hz version with the same secondaries is the 291BX. Because it is listed as GENERIC, match the 660Vct, bias, 6.3V and 5V ratings to your amplifier's requirements before ordering.
