Yes, the good old Amplivox or Racal Astrolite. I know they haven't been made for at least a decade but they were in production for what seemed like forever. Not cheap but robust, about a dozen different configurations and relatively easy to service and repair. They had them in the control tower at LBA for about thirty years.
This is one of three new-old-stock units I've recently acquired. Racal label still attached. They came with NATO stock numbers so probably destined for the RAF.
