Don’t know if this is of interest to anybody but if you go here, http://www.vmarsmanuals.co.uk/archive/files_index.htm you can download (for free) the manual SD.0165,AI Mk.IV and Ancillary Equipment, which includes diagrams of the AI equipment layout in Havocs with and without Turbinlite. It’s item number 258. There are also lots other interesting bits of radio/radar kit on that site as well.
