Unfortunately putting the PSU in the same box makes it subject to approvals which adds cost. Are you sure you can't use one of those black-case TPA3255 Chinese modules with an external 50V switchmode 5 Amps in-line PSU ?</div>

<p class="x_MsoNormal">Does anybody have an idea for an inexpensive 100w@8ohms mono audio power module
</p>
<p class="x_MsoNormal">That would have its own supply from 120vac?</p>

<p class="x_MsoNormal">There is a lot of cheap chinese audio power modules available</p>
<p class="x_MsoNormal">But they all need an added power supply (transformer, bridge, caps).</p>
<p class="x_MsoNormal">I’m looking for some kind of Class D power module that would only need 120VAC.</p>
<p class="x_MsoNormal">Audio in, spkr out, 120VAC supply. That’s it. </p>

<p class="x_MsoNormal">Any idea ?</p>
