Indicates, in one simple operation, whether transistor has had catastrophic failure and, if not, whether it can provide minimum data (gain) of 20 at 30 ma. Test circuit is inverter with emitter degeneration resistor R1 providing control of collector current during warm up of indicator lamp.-E. H. Sommerfield, Simple Transistor Tester Uses Lamp for Indicator, Electronics, 34:36, p 80.
