D-U47FET Build Thread
Let's get those Electron flowing.
All of the info: http://www.groupdiy.com/index.php?topic=49675.0
DU-47FET PCB set
Fits also Alctron Gt-2b style.
Not inclued in the Mouser Bom are:
The trimmer in this microphone PCB is no longer necessary , make sure you jump the potentiometer pad contact and use for R6 = 6.8K instead of 3.6K, the trimmer has been removed from the BOM As well to avoid confusion.
