I'm designing a compact but relatively high power guitar amplifier and am looking at power supply options. I could use a nice simple traditional linear supply with a big toroid but it's bulky and I think SMPS would be neater.
That said, I don't want to design my own SMPS for this project and so am looking at off the shelf solutions. There seem to be a few out there:
Connex High Efficiency Switched Mode Power Supply 300W / 72V. Trusted UK Seller. | eBay
or the cheaper:
500W +/-65V Amplifier Dual-Voltage PSU Audio AMP Switch Power Supply Board New | eBay
Has anyone used any of these or could recommend an alternative product? Ideally it'd have a +/-45V rail.

Hi Enzo,
Sorry, yes, that is the single ended variant but it is available in +/-45V too.
I'm just curious if anyone has used these or something like them for Audio. Having done a bit more digging, if I'm prepared to sacrifice power, I guess I could use a pair of Mean Well IRM 60 24s.

Here in Germany I've found and bought open frame SMPS modules of the same ratings as your Meanwells, but for only about € 5/ea. They can be series connected without any problems, thus giving ±48V rails, good enough for ~120W @ 8 ohms load.
Of course, for only 30W one pair would be sufficient.
Btw, do you know whether these Meanwells can be series connected without issues?
Best regards!

I can give the link to you later this day, as I don't have access to the website at the moment. Perhaps you might want to search by yourself at www.pollin.de.
Best regards!

I've taken a punt on one of these. It gives me a nice ~45V rails plus a secondary output for my preamp output and came in at a reasonable price.

There are a few reports of these being used successfully with chipamps so I'll I'll report back once I've tried it out.
