Wired
The simplicity of the amp dictate point to point, Jama is finishing his dual mono amp and pcb is a solution for a non existent problem.
Speaking about tastes the last word could be never be pronounced.
Best Regards for you gentlemen
Are we still looking into designing a pcb? This determines what type of transformers we need, wired or not.

First power on
Hello, this is my first power on. I have gotten 1.45A of current and 9mV of DC offset. I think this position of transformers is good. Input of Jensen is short.
The heatsink hot but it is possible touch it.. Load is 8 ohm power resistor. This is a good start....

Dear Lord I spy a Brony
Dear Tea-bag. I am not a Brony (and if I was, what?). I will tell to my daughter of 7 years old that her lovely wallpaper like very much between diy audio community.
And I think you do not need spy me. All is in the article.
Regards
Forgive me Jama if possible.
My behavior was out of line at your expense.
I have a hard time escaping my own juvenile mind at times.
Your leadership in this project is personally appreciated very much.
OK. No problem. I like very much this project. And since I joined to diyaudio, 10 years ago, I have wanted contributed something positive. It is a pleasure meet with others passionate people. And I have started before others because in October last year I buyed the Jensen and some VFETs after read the Zen Mod thread. Thanks to all.
First test
Hello again. I have done some measurements.
0. Equipment used, 1.jpg
1. From 20 Hz to 200KHz (with Zout=50 ohm), 3.jpg and 9.jpg
2. Gain in voltage aprox 3.5, 4.jpg, 7.jpg and 9.jpg
3. To 12 Wrms to 8 Ohm (10Vrms), appear third harmonic
