APP14GE discussion thread

This thread is as reference for the APP14GE.

So questions and comments are welcome.

APP14GE is a new DOA  that uses both a germanium transistor and some silicon transistors.
The germanium transistor is placed in the best point to make sound.  As my MA1 preamp, APP14GE, has an warm vintage germanium sound. It can use some different germanium transistors inside for having different colors.
I have designed it both for line and preamp stages.

Here is my result:





The sound is so sweet!!!!  Im very happy. Im used APP14GE (version with af106 transistor) in 312 clone (+-18V) and works great. Thank you Pier Paolo.
