This PCB can be used to build a Dumblelator clone.
 
By purchasing this board, you get access to full schematics and layouts tailored for my boards. I've documented the original Dumblelator design with schematics, layouts and BOM. 
 
Dimensions: 240mm x 35.5mm
 
NOTE: Depending on the batch, color of the PCB could be either gloss black or forest green. The two version are sonically equivalent.
