Q3=2SC1815

Hi Khaho,

Thanks for your reply

It appears that the 2SC1815 and the ZTX450/2N2222 do not have the same pin configuration!!!

Now I understand

Hi Zang,

Never mind, the honeymoon was more important

Thanks for your reply.
As I wrote just before, I did not realized that the pin configuration of Q3 you used is different than the one of ZTX450/2N2222.
Now things are clear

All the best...
