Yes, it is a daily limit.
The Zero Zone branded LPS I bought to use with my new @jkrichards & Son Analog Output Outboard LPS Card arrived today. I chose a slightly smaller 12V 3A unit in order to fit into a specific space in my rack. The 12V 6A unit @jkrichards went with was too big to fit in my remaining rack space. I also wanted a silver face plate and blue LEDs to tie in better with all the silver face plates of my 2 channel gear.

You can turn this brass screw to get voltage to read 12.0Volts. Or reuse LPS at higher or lower voltage for other equipment.
Please let us know how you like the unit. The six amp units are great. They respond well to after market AC and DC power cords too

I figured that little set screw was to trim the output voltage. Thanks for the confirmation @Vmax .

That is awful purty for a simple (not simple) power supply.
Have fun.

Can you turn off the LED and screen?
Not that I see short of cutting the LED power feeds.
That’s too bad. There’s a switch in that LED’s future if it was mine. I wouldn’t want to permanently disable it.
Not a big deal in my world. My rack is off to the side of the room and this new LPS will be stacked beneath a similarly sized Jay’s Audio LPS on the bottom-most level of my big rack. And like the Jay’s LPS which feeds my DSPeaker AM2.0, this new Zero Zone LPS will be powered on 24/7.

You do want to make sure your supply is putting out the correct voltage. Set it as close to 12.00 volts as you can using an external volt meter.
You will be happy with that one. It’s a great R-core power supply
Just cut out a bit of black electrical tape and stuff it over the window. Job done

It’s a good Idea to monitor the output voltage with that built in LED volt meter. I noticed mine went from 12.0v to 12.1v and trimmed it down to the correct voltage by connecting a volt meter to the output connector from the inside of the P.S. while everything was powered on. If you ever see the meter showing anything other then 12.0v then it needs attention. If you want to dim the meter just get a piece of lighting film (gel) they use on pro lighting and attach it over the window. They make neutral -stops.

Ted said that +/- 0.5v it’s ok.
I run my DS analogue board from a Keces P8. Usually is around 12.1v, but it already went to 12.4v once. Everything runs ok.
Can you explain if your concern is only with that specific LPS or general?
By the way, power wise, the DS analogue board uses 0.5A steady all the time.
Thanks.

Yes however some here have damaged the DS because of over voltage. The internal power supply measured 12.07 VDC under normal load. I set my external to the same to be safe. It’s best to verify and set the voltage as accurately as possible as if it drifts a little it will still be in a safe range. Why live on the edge?

Larger transformers sound better. If your doing the external power MOD I would recommend 2 amp minimum. I am running a 100 watt transformer (12v 6 amp) and it sounds sweet.

Agreed (safety wise).
The Keces P8 has overvoltage protection on 12.5V, so within the limits Ted referred to DS Analogue board.

The 0.5A is the actual DS Analogue board consumption.
The Keces have 4Amps available. Plenty of headroom. 
Hi Ted. Finally had time to dig through the info here a lot more, and even watch the intro video. Very nice and very informative!
Re: the AD8139- may I ask please, regarding the importance of the switch here- would you think it might be worthwhile sonically to r/r the AD8192 in place of the (8) AD8132? I can do the rework and willing, if it might uplift the sonics. I have an order of (10) qued up at Mouser, pending what you might add.
And after probing around the board/switches today with the scope I have some other questions around the switches here but will post in a new reply.
Thanks! T
Finally had the chance to do some probing today around the switch circuits. Was rather surprised by what I saw really. I think you alluded to it in the intro video, but it seems there is already quite a bit of LPF happening at the switch circuit already. I was under the mistaken impression that there was ~ none, based on an earlier question I had about filtering around there.
So I had assumed we’d see raw bits firing into the transformer, pretty much. But no, they’re being fed what appears to me to be quite an LPF analog softball already really;)
In fact I could not really even find much/any ultrasonic content on a test sine wave at switch circuit output B in the image below. That surprised me. I do only have a lowly old Tek TDS224 4x100MHz DSO at home, but still…
-From what I see it seems we could even just block the CM DC and send the switch circuit outputs straight out the back of the DAC, if we wanted, no transformer Hmm (gears squeaking here)…
Also, assume those differential filter caps at A and B are PPS film caps?
Nice job, and how rewarding to see all your efforts turn out so well
