There is a 600VA transformer but that will be reclaimed unless you want to pay for it. PSU caps are not big enough, the PSU needs a serious re-vamp.

Please don't ask for parts of it. It comes as an almost finished project.

It has been run and fully tested. It's all set up ready to go but the cheap caps are too small for a Class A amplifier.

There was a pre-unreg PSU prior to the cap board. This has been removed and used in another project. Hence there is no recitfication after the transformer.

This amplifier needs SERIOUS CRCC PSU. 42000uF per rail was woefully insufficient.

I say again, transformer will need to be negotiated separately otherwise it will be removed.

I use Aleph Mini every day (with seriously attenuated input signal) which sounds better than my ACA but sound pressure wise ACA was really enough 98% of the time... Still I can imagine that bigger Pass amps would be better even at my low volume level listening. So I was tempted to try. But you probably don't buy a brewery when you want to taste a beer.
