Two AM7/3 Internal Send amplifier modules (BBC codes AM7/3/213 and AM7/3/1638).

These audio-frequency transistor amplifiers were primarily used as the output amplifiers for studio desks. AM7/3 amplifiers were designed with a low output impedance (55 ohms) to allow for their use with longer runs of capacitive cable in the new BBC control rooms, due to the large amount of switching equipment.
