BBC ATM/1 AC test meter (valve), 1960. The ATM/1 was used as either an amplifier detector or a test programme meter amplifier. A 600-ohm input jack and a high-impedance input jack are provided on the jackfield.
It was a rack-mounted component which formed part of BBC's A.C. Test Bay AC/55, a 19-inch bay of equipment for the audio-frequency testing of sound apparatus and the audio-frequency and direct current testing of lines. At small centres where the full facilites were not required the bay was supplied partially equipped as necessary to suit the requirements of the particular station.
