Yes but schematic and layout is not enough to made D2000, you must have expirience, instruments and you need my help if something go wrong. I suggest to everyone to made D200 for start.

Hello. For d200.1 need a preamp? I think the output of my computer does not provide correct voltage to the input of the amplifier.

Can you post schematic of this filter? You can add gain in filter circuit so you don't need preamp.

Replace R23 use 47k instead 10k and you have gain 5X
