5.Recommended Spare Parts 5.1 Sensor and head amplifier

Sensors and head amplifiers are supplied as integral items, and therefore no spare parts are available. In the case of sensor mounted head amplifiers, the sensor is attached to the head amplifier, and the two are not usually available separately.
