The 290CEZ is a 290 Series replacement power transformer for a Vox guitar amplifier, listed for the Vox AC15C1 (reference only). With a 120/240 VAC, 50/60 Hz primary, it suits technicians servicing that amp on either mains standard.
The part drawing shows two 120V primary windings (BLK - WHT/BLK and BRN - WHT/BRN, 50/60Hz) and three outputs: ORG - WHT - ORG 600VCT @ 120mA, RED - RED 25V @ 250mA and YEL - YEL 6.3V @ 4A. Drawing test data lists 180mA (TYP) excitation current and no-load voltages of 315V - 0 - 315V, 26.47V and 6.618V (± 2%), with the second primary at 120.0V.
- DC resistance at 20°C (± 20%): BLK - WHT/BLK 4.871, BRN - WHT/BRN 5.221, ORG - ORG 121.0, RED - RED 2.678, YEL - YEL 0.043 ohms
- Hipot: 2500V, 60Hz, 1 sec primary to HV secondary, primary to core, HV secondary to core and primary to secondary; 600V, 60Hz, 1 sec secondary to core and secondary to secondary
The drawing gives dimensions including 3.000, 2.935, 3.610, 2.500 and 2.000, is marked E207860, TYPE: 3AH ED, and made in Canada. The winding is bobbin. As a 290 Series part the 290CEZ is designed for drop in replacement and to preserve the stock "tone". It ships at 7.65 lbs (3.47 kg), is RoHS and REACH compliant, and carries UPC 623980284224.
