Hi all,
especially for those high power AX-topology amplifier a SMPS might be a cheap solution.. After some searching I found this:

and especially this one:

Do you think it is diy-able.....

LOL offcourse not... but I'm sure I will after some significant time reading all I can find on SMPS.... So far this seems this most simple SMPS suiteble for an audio amplifier ..but I if any of you have suggestion, I would be very interested..
I cann't seem to find any web pages with audio SMPS projects.. anybody got some links?

Thijs,
No links, but I have been using these for some time now:

Just add a bridge and capacitor up front, and you have highly regulated, fully protected, 2 x 150W supply.
Maybe not what you want, but a nice example of contemporary technology.

tschrama said:Nice, thanks for the link! I have looked up the prices:254$ for a dual 48Volt/150Watt modules ... although the look great, state-of-the-art, it isn't price competetive compared to a conventional DC supply and not very DIY...... but it is tempting!
If you need 48V switching supplies -- I have a bunch from Sorensen -- very, very low noise -- they aren't particularly low-weight like current production switchers,
48V will be very exciting in the next couple of years. Stay tuned.
