Hi everyone.
I've ordered recently a pair of toroidal 200W trafos with two secondaries of 25VAC, which results in about +- 35VDC.
The question is, which of the locally available chips should I use. The load will most probably be 8ohms, ~40W RMS towers. The best price/quality ratio chips here are LM3886 and LM4766. The first one wants 4ohms, the latter 8 ohms to show all their might. Now, if I get a pair of them per channel, I could bridge two LM3886 and get roughly 200W. And they would be quite happy with +-35V voltage.
The other option is to take two LM4766's and bridge/parallel them, which gives us around 180W. But their supply voltage limit is +-37V, so I could easily get nasty side effects from SPiKe.
Particularly, I don't see much difference in these two choices. Do You?
Any comments are welcome.
