AVO 160 VALVE TESTER, 1960's

Useful for testing Military valves as well as commercial types. Basically the 'Automatic Coil Winder and Electrical Equipment Co.', Douglas Street, London SW1.
Later renamed to 'AVO Ltd.' (which should not be mixed up with 'Avo International Ltd.)
AVO is well known for it's very solid and reliable measuring instruments, and coil winding machines.

Your comments:

• I work in a calibration department that still see at least 2 of these units each year. They are still in use and are as accurate as they were when they were built.
