Transistor checker tool with circuit


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.
Transistor checker tool with circuit

Part List :

R1=330R/0,5W
R2=27K
R3=1K
R4=1K
R5,R6=5K6
C1=1uF
C2=2,2uF
Q1=Socket transistor
T1=Transformator output (OT)
S1=Switches friction
G1=3V
X1-1,
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.
