I bent the VR14 standoff upwards to clear the via.
I found another diff between the PDF BOM (maybe that one is not kept updated?) and the build instructions for the SEQ. R694 (going towards the LCD) is 220R in the PDF and 1.2k on the build page. If e-lick is not updating the PDF he should delete it.
Edit, checked the schematic and it says 220R... Any ideas? 1k2 or 220R?
Edit2 and on the build instruction page picture R694 looks like it is 220R
My build log - missing parts, questions and suggestions
All LED resistors in the schematic are 220 which is fine with normal LEDs but the ones supplied in the BOM are probably high efficient.
I used 1k2 for all LEDs wich gives good brightness.
For the LCD from the mouser BOM no resistor is needed as the new haven already have them on the display board. so use a jumper/resistor leg/ wire there...

Finished mine today with the following parts missing from the original BOM:
Hihat:
x C159 - 100pF, ceramic
HiTom:
R386 - 68k
C95 - 0.1 uF Film cap
Handclap:
R226 - 68k
Bassdrum:
X C4 - 100pF ceramic
Ride:
x C140 - 100pF ceramic
Crash:
RA11C - 20K
X C50 - 100pF ceramic
Seq:
Resistors 1.2k - 41 units
IC 115 replacement eeprom
- LCD pins
- LED stand offs - 4 units
The ones marked with X I replaced with a 50V instead of the 100V spec.
Update:
Master:
R472: Missing 470k resistor.

My Ride was noisy and overdriven with up to 14,7V at the output,
With help from comboy and nordcore we figured out a defect sa798 transistor.
If you run with a 909 or clone in same issues, check the voltages there.
It was hard to find the rootcause.

Hi guys,
I finished mine yesterday, but with an issue.
The Rimshot is not working... It's triggering, but on main and single out it just does some loud noisy crackle sound.
Does someone know how to fix this issue or how to find the broken part? I already checktd the resistors and SA1115 transistors, but the seem to work correctly.
Thanks a lot,
Jule

Found one more silk screen error. The trigger arrow for Hihat is pointing at the wrong resistor.
just wondering why so many components were missing - just mouser boms were not perfect - or are these parts from the included components that come with the pcb?
Seems the BOM was not double checked before posting. And I guess noone at e-lick actually tried to build a sample using the BOM.
Ah ok - huge thanks for your efforts guys
My NAVA build is working now! For all the people who are still building:
It is very important that you use CD4011UBE chips or the Hats won't sound right! They are correct in the BOM but if you use your own sources you should be aware of that.
Also test your "2SA798" Transistors if they are working!
@Vincent:
I had 2 parts that were broken which came with the kit:
1x 2SA798 Transistor
1x M5218L Mitsubishi IC
It'd be nice if you got back to me and send me replacements for the broken parts!
