Here is a 24v 6A switching supply for very little $$$. Free shipping too. I can't buy a decent transformer and caps for that little. The brand is Meanwell and we use them here at work so I know they do work and have been reliable. A big plus is the current limiting too.
Since (2) 24v supplies are needed to build an F5, wouldn't this be a reasonable way to power the amp?? I do think that a SMPS should be remote from the main amp chassis with plenty of EMI/RFI filtering between the two. Obtaining high current connectors are not a problem either, I think. Am I missing something here??
Thanks for any comments,
Bill

SMPS tend to get a bad reputation by the audio community. The PS in that link lists the switching frequency as 25Khz which is pretty low. I would want something much higher, say 100Khz minimum.
If you did go the SMPS route I would add some more low ESR caps and ferrites to clean up any leftover noise or ripple. Of course an oscilloscope will greatly help 🙂
