I bought this as a parts backup for an Alexa I used to have, however I never needed it and never took anything off of it. The sensor, circuit boards, fan, are all still inside.
Also includes a 3-pin XLR to Arri 2-prong power cable, and a new spare fan.
Basically these are all the spare parts I had in case I needed to upgrade/repair an Alexa I no longer have so it's time to let them go.
