EFIE Circuit Boards

This series includes just the circuit board for an EFIE. The customer must provide his own enclosure, switch, and means of connecting your multi-meter leads to adjust the EFIE. The same circuit board is used as in all other EFIE models. It works just as well. It is only missing the conveniences found in the Deluxe series, or the protection provided in the Basic series models.
