The tester is rare! There is no such thing on ebay
Sell my transistor tester, which is ideal for germanium / silicon transistors.
It is good because it tests transistors at the current required by the transistor!
Not like the Chinese Tester 0.5-1.2 mA....
Measures HFE / Leakage / Performance (tests without desoldering)
Tests high - power and low - power transistors
Made for 9 - 12 V DC
I have several of them and want to give them to good hands.

I will answer all questions and tell you everything! 
I am confident in it, it has not let me down and will not let you down! This equipment was made to last for decades!!
