Oppo UDP-203 Reference Digital Power Supply for DIY install

DISCLAIMER - We take no responsibility for damage to your OPPO with a DIY installation.

Note. This psu only powers the digital circuit and will not power the analogue 5.1 pcb. This is for the ultimate digital performance where HDMI is used for audio.
