The FET buffer can be powered directly from the fixed +5 V supply on the ALM1000 analog connector which will limit the allowed range of analog input voltages to be somewhat less than the 0 to +5 V supported by the analog inputs because of the headroom needed by the source follower and the current source Boozhound Laboratories (BHL) sell a partial JFET phono preamp kit that consists of a printed circuit board (PCB) and the passive parts .
