A Letter From Larry Andrews. Pres/Gen. Mgr. NB Labs

NB Labs Has Built Over 20,000 Electrodes.

  Pinouts - Features - Contruction Options

Channels 1-16 have JFETS
The ground and the stimulation channels don't have JFETS.
Ground  #1 can have a JFET if needed for differential recording. (At no extra charge.)
Note: VDD + 9v or 12v (DB25 #1)

16 Channel JFET Headstage DB25
