In the case of the power supply, no expense was spared. After
all, the power supply is one of the primary factors in the audio
quality and overall sound of any device. Just like the best coffee
beans in the world will not produce a good cup of coffee with
poor water, the best circuits can’t produce a great sound with
unreliable, inconsistent current. The transformer delivers three
different voltages, each of which is separately screened and
regulated: 250-V anode current for the tube, 48V for phantom
power and 2 x 15V for the audio signal path.
Critical currents are stabilized via a 100-nF MKP foil condenser,
to ensure sufficient current for even the shortest impulses.
The transformer is encompassed by double shielding to keep
magnetic stray fields to an absolute minimum.
An AC power cord is included for connection to the standard
3-prong IEC connector. The transformer, power cord and IEC
connector are VDE, UL and CSA approved. The AC fuse is rated
at 315 mA for 220/240 V and 630 mA for 110/120 V.
