My TOTeM project

[Goldmaxx]

Hi to all,

I currently have some time, I will here show the construction of my TOTeM project.
Since I am not a electronics expert and I hope that I maybe get some help here.
The theme PD has always fascinated me and I very much fun to construct.
It will be my first PD project and am very excited.

At this point, I would like once more to thank so much Qiaozhi and Carl for the wonderful book Inside the METAL DETECTOR, which made ​​me very thrilled.

So the PCB I have almost finished, there only missing the transistors.

And here was already my first question to Qiaozhi:

There are three different versions of the BC108 transistors A, B or C.
Which type do I need, or are they all the same?

Thank you very much

best regards

Here are picture of my PCB
