Without alteration to the original circuit, the PSU1 is now certified to IEC, UL and CSA 60950 standards. This enables the sale and use of the PSU1 in many countries that require and mandate standards of excellence for product safety, quality and performance.

The PSU1 is supplied with (standard versions of) the Era Gold V, Solo, Elevator EXP, Jazz Club, Era Gold Reflex and Revelation. It is an optional upgrade for the Gram Amp 2, 2SE and 3 phono pre amps and will extend their sonic performance.
