I'm building an O2 amp, which according to the designer requires an AC-AC adapter (Triad WAU 12-200) to convert regular wall power to 12VAC. By looking at the schematic for the amp however, it seems that I might be able to use a regular AC-DC converter (also 12V) instead.
According to this site, an AC-DC adapter uses a transformer to stop down the voltage, rectifier diodes to make the current DC, and caps/regulators to smoothen it. Now, the datasheet for the WAU 12-200 shows the following as the adapter's schematic:

It would seem that the WAU 12-200 merely acts as a simple transformer. Meanwhile, the following equipment is present inside the O2 amp:

After entering the O2, the AC power goes through a set of diodes and caps/regulators just like what would happen in a AC-DC adapter. Not that I don't plan to use batteries in the amp at all (strictly wall powered) so the "battery power" section of the amp in the schematic should be omitted.
I've got a 12V AC-DC adapter that delivers 200mA (same as the WAU 12-200). Is it possible for me to omit the diodes and caps on the O2 board and feed it 12VDC power instead?
