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

Connection
Input Voltage Selection
Input voltage comes pre-configured for the country originally shipped to.
If the input voltage needs to be changed, jumpers can be re-configured on the internal selection
plug.
To access the jumper selection, you must remove the PCB from it’s chassis. Remove the 4
corner screws on the back panel and the single screw on the bottom. The PCB assembly will
now pull out from the rear. A small flat blade screwdriver can be used depress the locking tabs
to remove/move wire location in the jumper block.
see the diagram below
120 Volt (2 Jumpers) 240 Volt (1 jumper)
Re-assemble in reverse order, being careful to align the power LED with the front panel opening
before pressing in all the way. If needed, remove the front panel and re-install last.
