This vintage Bach Auricon Pro-600 16mm Movie Camera includes the Auricon MA-11 All Transistor Filmagnetic High-Fidelity 16mm Sound On Film Amplifier with user manual.  Also included are travel cases for both units, the Bach-Auricon Duplex AC Power Pack and Battery Charger, headphones, all associated cabling, and everything else pictured.
 
Testing Performed
The Pro-600 powered up with the take-up motor running. With the black button on the back pressed in, the light indicating that the thermostat controlled heater is on, goes off. There is no indication that the initial start-up power is being increased though. The red stop button on the back didn't do anything when pressed, but I'm not sure if it would without actually having it running with film in it.  The battery for the sound amplifier is not included, so the AC power pack was used to provide power to the amplifier. This unit powered up with no issues. Using an Auricon E6 microphone (not included), audio was received with no issue through the headphones.  Only 2 of the potentiometers in the amplifier were not sealed potentiometers, so those and the switches were cleaned. 
 
The Bach Auricon pro-600 is an academy aperture 16mm camera that runs at a sync 24 frames per second.
