Power Supply

The power supply was carefully engineered to provide clean and consistent currenttttan

important prerequisite for excellent audio. Built around a toroidal transformer, the power

supply generates a minimal electromagnetic eld with no hum or mechanical noise. The

output side is ltered by an RC circuit to extract noise and hums inherent in commercial AC

power.

All audio-related components are fed by two separate voltage regulators to minimize distur-

bance from other components.

An AC power cord is included for connection to the standard 3-prong IEC connector. The trans-

former, power cord and IEC connector are VDE, UL and CSA approved. The AC fuse is rated at

500 mA (230 V version) or 1 A (115 V version).
