This is the same SMPS that I use in the Jupiter Preamps.
It has a universal AC input ranging from 95-265v
It outputs 260vDC @ 160mA for the B+ and 6.3vDC @ 4.5A for the filaments. The B+ supply can be adjusted +/- 10%
These are very compact units measuring 100mm x 58mm x 32mm (L,W,H) so they are perfect for 1u rack enclosures.
