My ARU-11/A ADI taken apart, showing its spectacular mechnical core.
After obtaining my HSI for relatively cheap, I thought about other instruments that are difficult to develop by myself. The one that immediately came to mind was the ADI.
The collector I got my AF/A24J-1 from also happened to have an ARU-11/A for sale, so I managed to buy it for a mere 170€ in June of 2020.
