The above sequence is a circuit of development of the transistor circuit tester before, which of course added few more components , and resulting in even be better. Examiners transistor circuit above only knows his gain is only on the collector . In addition to well known techniques of data materials used therein . That is , if the elements germanium and the like which are in the tool is still functioning or vice versa.
R1=330R/0,5WR2=27KR3=1KR4=1KR5,R6=5K6C1=1uFC2=2,2uFQ1=Socket transistorT1=Transformator output (OT)S1=Switches frictionG1=3VX1-1,X1-2=Speaker connector
How to test :Emitter associated with foot condensator and resistor R4, Base is connected with one leg transformer OT , The Collector is connected to the foot of R2 and R3. If you hear a hiss , the sound in few seconds it still has not changed means that transistor still disqualify technical data.
