[sdiy] Any idea for an inexpensive 100w at 8ohms audio power module (supply included)

[Mike Bryant]

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 ?

Does anybody have an idea for an inexpensive 100w at 8ohms mono audio power module

That would have its own supply from 120vac?



There is a lot of cheap chinese audio power modules available

But they all need an added power supply (transformer, bridge, caps).

I’m looking for some kind of Class D power module that would only need 120VAC.

Audio in, spkr out, 120VAC supply. That’s it.



Any idea ?
