Sure 4x100w and Xformer
 

I just need to use this as a 4 channel home theater amp for the (2) rear, center and sub.

Don't listen loud -- the spkrs are small -- even the sub isn't a "brute".

I have a 24v 4amp transformer here which I can build a power supply with and it "looks" like I may be able to get away with using it as long as I don't push it.

Anyone have this board and can comment?

(Not looking for info on SMPS blah blah -- just if anyone has used a 4 amp supply.)

Thanks much.

Running 4x100W amps off a 100W supply isn't optimal, but as you say, you don't need all that power.

I'd say it'll work fine - give it a try.

Are the speakers same brand/model as L/R? Might be a bit tricky integrating levels etc.
