I actually have one more of the full PCB set for the amp with DCDC and Cap Mx PSU, input select board, CLC filter, volume pot helper board, Xfeed board etc.
Good news is that I have plenty of the stand-alone amp boards but they have an easy to fix error (wire jumper and 2k2 resistor needed - see photo). These work great and are ideal for the DIY’er wanting to use his own PSU or to make a balanced (BTL) output amp.
The standalone boards are available here:

You might also be interested in the SSR headphone DC protection circuit if you are going to make this amp.

Just tested out the standalone boards with the Yarra PSU. It sounds fantastic! I forgot how good this headphone amp sounds. It is so direct and powerful. DC coupling makes a difference I think.
I might have to build another set of boards and make a balanced output headphone for myself.

I got two times fake BF862 - giving up. How about the 2SK209 ? What is needed to be changed when using this fet ?
How about something like the 2SK3557? I've not tried them before but dirt cheap and plenty available at Mouser.
Of course.
Possibly can be used as well CPH3910-TL-E but I'm not sure it would be as good as the 2SK3557

How did it work out? I'm dipping my toes into the whole smd thing and wondering if something like this will make my life easier...
It works great but probably overkill for the hobbyist. I was working on a project with 700 parts so it made sense.
For most projects up to 200 parts a much less expensive manual dispenser like this works fine and is what I use most of the time now.
