Test carrier signal is added to input of normal amplifier A1. When failure occurs in A1, detector senses absence of test catt'1et and causes relay K to change over to amplifier A2. Both amplifiers ore differential type, having open-loop gain of1,000 and closed-loop gain of 10. Open-loop response is flat to about 2kc, and closed-loop response ex tends beyond 5 kc.-T. B.
