  • 260V @ 170 mA high voltage secondary

The 290XEX is the 240V @ 50/60 Hz version of the 290 Series power transformer listed as a replacement for the Fender BLUES JR. (reference only). It suits amp technicians and owners replacing the mains transformer in a Blues Jr. operating on 240V.

Its secondaries are 260V @ 170 mA (Secondary 1), 20V @ 100 mA (Secondary 3) and 6.3V @ 3A (Secondary 4). The manufacturer's short description reads 240,50Hz-330V/6.6V/20.5V 15W. The series ordering table lists a bobbin winding.

All 290 Series transformers were designed for drop in replacement of the original units, to look similar to the factory parts where possible, and with material and design specs kept as close as possible to the original to preserve the stock tone.

The 290XEX has a shipping weight of 2.55 lbs (1.16 kg). It is RoHS and REACH compliant, with UPC 623980037356 and UNSPSC 39121301. The 117V @ 60 Hz equivalent is the 290XX. Because the amp model is provided for reference only, compare the 260V, 20V and 6.3V winding ratings with your existing transformer before installation. The series ordering table lists no similar amp part number for this 240V version.
