Hi to all, i think this is my first topic here, i started learning electronics and it has taken me many years to understand the basics ( yeah .. I'm slow ), now i´m reading the Teemu Kyttälä book and have found  the "Totem pole and topologies using output transformers" section in this book, to my it´s  very interesting because i´m planning to build a hybrid amp, pre amp of a Marshall jmp (the pre amp is done) and transistor power amplifier.  I would like to have a tube sound, that´s why i´m very interested in this type of power amps in my build, but I wonder if there is material to read or circuits to experiment that someone can help me for a beginner. :dbtu:

thanks for your time, and many greetings to Juan Manuel Fahey,i know he is follower of this forum.
