If someone from the US is able to build one of these using my A4000D motherboard, this would be great!

These resistors here labeled as ERxxx should all be ferrite beads.

One of these PCBs made into my hands to build and right mouse button didn't work, even though I was able to get to early boot screen with both buttons. Clicking the button was not dropping the voltage going to the associated Paula pin low enough. Replacing the 200 Ohm resistor with the FB solved the problem. Here is a close up from the board I have before replacing them.

Coincidentally 3 of the same FBs were also used on the top side of the board and they were populated correctly.

Other than that, everything else worked fine.

Yes I check now you have right all this Bath have this R200 but should by ferrite beads
As well is another mistake
2 X transistor NPN is WRONG
Must change for correct NPN

Sorry for problems I not see this b4 my self soldering now 5 boards from this bath

Q300 and Q901, right?

 

[Kulamario123]

Q300 and Q901, right?

yes

 

[dava1973]

@Kulmario: Could you please specify:

• Which batch is affected? Who of us buyers got an affected board?
• Correct parts to be soldered as repair, especially the transistors:
  • are really both npn or is that a typo?
  • If both npn: what's the difference / which are the correct specs?

...and yes, I know about the BOM and the online placement tool, but it would be nice to specify the repairs here for reference / to shorten our search

Thanks in advance!

Q300 and Q901 need to change for 2N3904
As well on bottom side need change
all R200 for Ferrite beads

My board arrived today - yeah! It was held by the customs of my country for quite a long time - but now i have it and it looks really good! Big thanks to Kulmario123 for the board AND for the clarifications about the smd parts that have to be replaced. I will give feedback right away - and again: Thanks!
