Dead transistor ?
« on: September 23, 2011, 08:33:46 PM »
*first sorry if my english is not perfect,

so my question is: If a transistor can be half broken, I have old ac128 and I'm not sure if they are working,

 I check with my multimeter (check diode), and between B and C :136
                                                              and between B and E :137

the reason why I think they are maybe half broken it's because my porjet does'nt work ....but maybe it's just the projet...

But I want to be sure that my transistor are working

I'm french, sorry for mistakes

If you measure a certain value through your transistor, there should be some current flowing.
Have you double-checked how you placed your transistor? Have you made sure that your pinouts are correct?
If you placed your pinouts wrong, the transistor won't work at all...
