God’s Box – Loose Fruit 

Eurorack DIY Kit 

Instructions 

Version 1.1 

 

 
 
20. 
 
Now solder the two J105 JFETs as 
shown. 
 

NOTE!

  Orientation  matters  –  be 

sure  to  match  the  curve  of  the 
body to the PCB silkscreen. 

 

 

 

 
21. 
 
Next  place  and  solder  the 
remaining  male  headers  on  the 
bottom PCB - these are placed on 
the same side as the resistors and 
capacitors as shown. 
 
These  should  be  soldered  flush 
and  perpendicular  to  the  PCB 
surface. 
 
 

 

Bottom Board 

 

 

 
NOTE!

  Don’t  solder  these  headers  to 

the  other  side  of  the  board  like  the 
power header you already soldered!

 

 

 
22. 
 
Now switch to the other PCB and 
place  but  DO  NOT  SOLDER  the 
female headers on the top board. 
The  female  headers  sit  on  the 
opposite  side  to  all  other 
components as shown.  
 
Before  soldering  these  headers  – 
connect them to the male headers 
you  just  soldered  on  the  other 
board.  Once  you  have  the  PCBs 
connected nicely with the headers 
sitting  flush  you  can  then  solder 
them in place. 
 
Now is also a good time to screw 
the hex spacers onto the top PCB. 

 
 
 

SWITCH TO OTHER PCB!
