Next year when I rebuild my 6V6 preampL-Adapter has even been used for powering heaters in vacuum tubes.🔥
Its not the analogous of Ubib but has a wide range of practical uses.Sr Salas, Can you give me the link for L-adapter power supply?
L-Adapter thread
As you know, I already made several ubib sources and they are wonderful, the sound of the dac improved a lot and I am very satisfied, the consumption of each channel of the dac is only 70mA and I put one ubib for each one, the noise levels are very good, much better than with other types of sources that I had experienced. But it is true that when I did tests with ubib with larger currents the noise was worse.
But for other applications with more current needs of 3A or more, I'm interested in L-adapter, I don't care that it has worse noise than ubib.
I have already seen the L-adapter schematic, I see something simple, a ccs with led voltage reference and an "outboard" transistor to add current. Do you think it will be better for noise than a commercial three-terminal regulator?
For this circuit, LEDs blue is good for reference voltage, or is better standar LEDs green or red?

Then it should have no sweat with a NUC7 with a 10W tdp J4005 that I plan to use for REW, MiniDSP and Roon. Feed it 19 V?I have a NUC i3 that I use mainly for music. If you want the exact version let me know, as I do not remember now.
