The 291ZEZ is a 290 Series power transformer listed as a replacement for the Fender BASSMAN 135, Silverface chassis, with similar amp P/N 13830 (reference only). Its 120/240V @ 50/60 Hz primary lets technicians fit it on either supply voltage.
The high voltage secondary is 364Vct @ 1A. It is joined by a 53V bias winding and two 6.3Vct @ 7A windings (Secondary 3 and Secondary 4). The short description reads 364VCT,@1A, 53@1A, 6.3VCT 7A. The series ordering table lists a paper winding.
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 11.65 lbs (5.28 kg). The 291ZEZ is RoHS and REACH compliant, with UPC 623980142760 and UNSPSC 39121301. Compare the listed ratings with your existing transformer before installation, since amp model references are for reference only. The two 6.3Vct @ 7A windings are listed separately as Secondary 3 and Secondary 4.
