Power P3A with SMPS?

[invaderzim]

Is this SMPS: https://connexelectronic.com/product/smps300re/
suitable for the Rodd Elliott P3A amp? https://sound-au.com/project3a.htm 60W class AB

I know SMPS have come a long ways but I can't shake the years of "look how big of a transformer this amp has" so I just want to verify that it will be fine for it.

thanks,

Here is a Mosfet amp of comparable power equipped with the previous SMPS300R version.

now you've got me looking into the AEM6000 amp 🤔

Having built both, the AEM6000 is clearly the winner even if more complex.

It is almost time for another project. Is there someone that sells the boards or did you have them made off of gerbers?

Suzy is providing the gerbers that I have used. Beware that some components are a bit hard to find.

ahh, the fun of tracking down parts, made even more fun recently.
