@Mrlynx I ave seen that, but as i se it:

First of all, this is a real nice project.

r1-r4 : ?
r5-r8 : ?
r9-r12 : ?
r13-21 : 4.7 K

part list say's : R1-R21 10×4.7K (472) 4x1K (102) 4x10K (103) 4x120k(124), if you add the numbers it give 22 pices

@Mrlynx do you have a components list for resistors and capacitors, the schematic shows only r1 c1 not the values.
