BF862 based SE Class A Headamp without the HEAT

It looks good but my headphones are AKG712-812.
What happens if we put a few more 2sk209bl?

Each is good for maybe 10mA. You need about 120mA for 32ohm cans. You might want to match those JFETs to reduce chances of current hogging.

Because I have some smd 2512 resistors, I thought of making a pcb for them.
The output capacitor will sit horizontally on the pcb, not vertically.

Nice work. Looking forward to seeing the build.

Where can I get the bf862? because I had order it on ali, but these are mosfets reprinted, I am
for a punishment for this sellers, hoppa into jail.

There are maybe good ones, but difficult to see.

By the way Europe Union is started investigation into this fake business from China and ali/ebay.
