I bought the DM-2 PCB, the boards arrived, but I don't know the electronic components and where to place them. Is there a Bill of Materials (BOM) available? Thank you.


EDIT.

I wrote the BOM from schematic is it correct?

2SC732TM-GR  eq 2N5088 

2SC945-P  eq 2N5088

2SK30A-Y eq J201 or 2N5485

1S2473 eq 1N4148

D3: RD5.6EΩ3 (5.6V Zener diode)

D4: RD11EΩ3 (11V Zener diode)

LED: SLP 135Ω (red LED)
