VDC7 MKII High Current Upgrade Power Supply

Thank you for purchasing the VDC7 MKII High Current Upgrade Power Supply.

Please read the Connection sections of this document before installing into your playback

system.

The VDC7 MKII is a low noise high performance power supply designed to improve the sound

of many audio products. The VDC Series are tightly regulated "Linear" supplies rather than

standard "switching" types, as switching types generate noise which can contaminate audio

signals. The design uses a high quality transformer, discrete Schottky bridge rectifier, and low-

noise filter/regulator circuit, providing clean, noise-free power.

handcrafted in USA
