Hi,
I was planning to build the nice little amplifier described by Glenn Zorpette at IEEE Spectrum (Full Page Reload), however as he and others have noted, the 3e-Audio amp module does not seem to be available any longer. I have looked briefly at the long thread on here about amps containing this IC and searched online, but I have seen very little that might work as a good replacement.
Does anyone have suitable ideas for substitution? I am handy with a soldering iron and reading schematics, but I'm not really up to designing things from scratch. And having a decent premade PCB is a must!
Thanks,
Phil

This IC was very rare in module, nowadays tpa3251 also disappeared leaving the high power tpa3255 only available for about 50$.
The 3eAudio 3251 boards are readily available, on AliExpress for example. The 3250 and 3251 chips are almost identical...

A weak ago I saw this item, it was available.
