I have a Teddycap+ PS which powers my Naim 72. It also has a NAPSC supply a with a 2 pin output which is 18v. I want to change the PS on my Mac Mini to an external DC 12v - min 4.5 amps. My guess is that if I can make this work the TP can be an optimal PS for my Mac Mini which is a dedicated music server. Teddy makes a cable that converts the output to the required 5.5/2.5 barrel jack.
Can one of the electrically savvy members tell me if it would be difficult to drop the output on the NAPSC output only from 18v to 12v. Here is the description on what is required for the PS. "The 12V input connector to the MMK is a high quality 5.5mm x 2.5mm DC barrel jack (center pin positive). To boot and operate a Mac mini that has been converted with an MMK requires a 12V power supply capable of delivering at least 4.5 amps."

By the way the NAPSC output is used to power a Naim headphone amp or Naim phono stage. I just want to use that output for my Mac Mini music server.

Ok so 28 folks read this and no one answered. Either this is a stupid question or I did not provide enough information or my explanation was too convoluted and too much work to respond to.
Please let me know - thanks.

Yes. It seems a bit unclear w. Trying to do. Also, you will get very diminished returns by converting music server mini to linear, assuming you mean DLNA server. Much more info is needed on the NAPSC and they don’t look like the type of company to do so, but email them for he schematics and see.
Thanks for the reply. I will try to be more clear on my goal. I have a Mac Mini that is dedicated as a music server. It is connected to my Naim 72 preamp. My Naim 72 is powered by a Teddycap which has 3 24v outputs and one 18v output. I want to use the 18v output to drive my Mac Mini. Replacing the power supply on the Mac Mini is an important upgrade. The conversion kit for the Mac Mini requires at 12v supply. My goal is to convert the 18v output to 12v. I have a cable that will connect the 2 pin output on the Teddycap to the input on the Mac Mini conversion input. Is this as simple as soldering in the right resistor to drop the voltage?
Maybe "center of the World" self entitled people does not exactly attract answers. 🙄
You'll have to get the schematic or trace out the pcb and do enough reverse engineering to determine that. Certainly the internal power dissipation of the Teddycap circuit would increase significantly since it is linear.
That may be a big problem. I'd say it is unlikely to be possible.
