i am following this psu schematics :
this is the worse psu i ever tried!!!
very very big distortion, noise, and hum....
An externally hosted image should be here but it was not working when we last tested it.

nothing wrong electrically with it , but physically you need to make it completely opposite
star gnd must be positioned exactly between C14 and C15 (for R channel) and exactly between C16 and C17 (for L channel)
besides that , you need to make a bridge with fat wire between these two points
it's much better having two bridges config - Papa explained reasons for that (avoiding any possibility that nonsymmetrical load induce buzz in windings) ....... and - if having two (per channel dedicated) C banks , then is best that each bank have own 2 bridges
that way one can have almost dual mono approach , without need for mentioned fat wire between two central grounds

Hi, guy
Here're my oldy but goody Aleph 30
Thanks

My suggests - some years later ... sorry-)
Do NOT use channel-separated psus!!!!!!!!
Do not use thick wire, or copper-plates!!!!
Do not use mounts.
Do not crimp.
Do not use unlaqueured lace-wire.
Do use ca. 1,5 mm solid core. Not more!
How to bridge caps: 20 mF - 2 mF - 0,2 mF - and so on! The same types! One time per psu - an aleph has two, + and -, is okay.
Better - the same capacity as example: 10 x 2 mF or so, at ONE circuit,-!!!!!
Sometimes it is useful to try some points to set the "ground-star". As near as possible at amps and last caps I would try first.
And many/much more,-)

Yes you are right i wa in hurry 1,2 kVA = kW i meant.
Figure 8 Shows a regulated supply. Dont know how you make it dual mono?
Try this: A pair of mono-amps, listen......
Sorry no time for experiments at the moment. I,m ultra happy if i get my Aleph 60 done this year.
The only reason i asked why not to use channel-separated psus is, i will do exactly that in my build.
And if your explanation would have been conclusive maybe i have changed my plans.
You repeat the same supply and where you see the box labelled Other Channel Gnd that is where the other PSU ground is connected.
Forget the regulation, the same principle applies to CRC supply too.
No problem to build mono-psus and to connect per wire than. Set an extra jack (with "two channels") per amp before you will finish.
But note (the/some) other suggests to get a homogen, clear working psu.-)
And think about: How to set many devices (in a pair Aleph 60 are, as example, 4 x 6 End-Transen parallel,-?) at ONE circuit,-! It IS! important,-!

Why an Aleph 60? Do you want organize concerts or do you have unefficient speakers - 80 dB/W/m - or do you live in a hall?
May be, an Aleph 3 or Mini-Aleph is the better choice.
May be, an "Aleph-Zen" is the better choice: ONE psu, without different-amp in feedback.
Much more better: "Zen-XA".
What sort of speakers do you have? Multi-way? In big wooden cases?
