I finished assembling the components. Everything works very well. Thanks knauf1919 for pcb and lineup for sharing the project.
In the near future I will make a case worthy of this amplifier.

The best headphone amplifier. Glory to the one who designed it.
Love it. Thank you lineup and Knauf1919!
Edit: yes, BP output caps not needed... I had them laying around, not fitting any other application I have.

Which circuit did you use finally? Could you please post the final schematics of the BJT version including the regulator section? I want to build it!
a couple of questions. . .
With the 5v version, is there enough headroom for 5x gain, if line level output? If not, the 12v is fine.
Is there a preamp schematic available, perhaps with a TO92, such as BC337 or 2n2222, instead of the BD139?

Hi Marin Cornel! I look forward to seeing your DIY case!
May I ask why you have labeled your input and output terminals on PS board as "250R"?
Cheers!

Hello,
This is how they were marked with 250R. I don't know where I got them from. It certainly meant something in the set-up for which they were intended. I didn't remove that mark.
Hey Lineup, what is the point of C6? Removing it doesn't seem to do anything in the sim...
Can I have recommended version for 20k load and for 50k load, either with 6x gain and 12vdc supply?
Oh man, I've ever so much need of that!
I have so much amplifier projects that can't match up phone/pc/tablet commonplace sources, and therefore 3 transistor singleton-input single-rail preamplifier is hot on my wish list.
The other alternative is buy a better source, build another amplifier, repeat; but, unfortunately, that typical method doesn't result in fully-practical music outcome.
Is there a brand and/or type of headphones that particularly matches with this amplifier? Or, to rephrase the question a bit: what headphones do you use with this amplifier?
Reason for asking: the sound in the right side of my headphones (Beyerdynamics DT770 Pro 80) is gone, have to look for a new pair and could use some suggestions, thanks.
