Are there any cheap options for a Better Touch Power Supply?

[Rosewind]

Beetof.

I have not started the build yet as I have another must have box to buy first - a Linn Tunebox (external x-over) so that I may take my Linn Ninkas active with Naim pre- and power amps. But I Will make sure to report back once I have bought the "ingredients" and have become a better solderer than I am now. I have started my training programme ...

Best wishes,
Peter

That supply is a 12V design, do NOT use it with the TOUCH!

Hi John, I use your design with an SBT I have here. I am going to build another but I see that the scematic link no longer works. Did you ever do any revisions to the original design? Are you still happy with it?
I'm going to combine this with another 5V supply loop to power USB powered reclockers such as the AP2 as I can't be stuffed with battery mods.

I just ordered the parts to make John's PS, but will use the SuperTeddyReg in place of the LT1084. The other change I made was to get a Triad VPS24-3300. Teddy Pardo recommends a minimum of 11VDC for the the SuperTeddyReg.

3 pin regulated linear o/p PSU,5-24V 18W


It looks like it only supplies 2A I thought that would not be enough?


I am also still interested in any power supplies such as the one above that can be bought in the UK. I have had a look at the schematics posted earlier in this thread but for me personally I don't know enough to attempt building this.


If anyone has any links for any power supplies I could get in the UK that would be suitable I would be very grateful. At a reasonable price I am prepared to have a shot and see if it changes anything.

Hi
Try mark Grant cables or squeeze-upgrade.com.
This supply works in my system.

Finally finished my power supply build using John Swanson's design. I used a beefier power supply from Triad, Teddy Pardo superteddyreg, and a felix power line filter. It's not yet burnt in but I think mt Touch sounds better then the expensive power supply I was using. I purchased that power supply years ago for my SB2.

I'm using my Touch as a transport to feed my TubeDAC-11 via SPDIF.

Has anyone considered using the power supplies from partsexpress.com. They have a couple where you can modify the voltage to match the touch.

Here's the exact power supply:

I guess you don't have a way to ABX against the standard power supply?

I guess you don't have a way to ABX against the standard power supply?

easy enough to do. have another party change out the power supply without the users knowledge of which one and they can listen and note preferences in a double blind test. And yes, I'm suspicious in most reports of a new power supply creating noticeable differences (much less improvements, and of course they are always only improvements). Too much demand effect/bias here in sighted tests.

Have anyone used audio diff maker on the output of a Touch to objectively asses this ? ( I don't have good enough soundcard in my pc ) .

It was done by several members for the SB3 , conclusion the signal out from the devices does not change at all .

However a possible mechanism is interaction with your other equipment from the switch mode ps , in my case it would be unlikely as at least 5 other components in my hifi has switch mode power supply and thus are designed to cope with it .
Some more exotic components may not be very well designed re rfi/emc .

Was not that the design rationale behind the power supply John Swenson designed ? As such interaction can come from traditional power supplies to .

There is to much subjective bias anyway as no one reports worse performance with any third party ps all linear power supplies are not good and switch mode power supplies are not inheritly bad .

So why search for a " cheap linear supply" if one wants a cheap supply that is good ,switch mode is the obvius choice .
