With the more detailed information provided by Avii I queried Oppo again. Here is their reply:

We'll try to explain how the player is configured in more detail.

The direct power supply, the board which directly interfaces with the power plug, is a switching power supply. However, the switching portion of this power supply is only connected to the mainboard (digital and video processing board). The AC rail past the fuse is connected to the toroidal power supply. This section is linear as there is no power processing.

The toroidal power supply into a secondary voltage linear power supply designed to always have more voltage in the capacitors than the working voltage of the whole of the player. This power supply is only connected to the analog audio board.


Seems a bit devious to me, especially since I am trying to remove all switching supplies from the system.

So Nick, it looks like you have another customer for a BDP-95 supply.
