Hello all, I have been lurking around here for some time reading the whole F5 power amplifier thread, very informative and helpful, and also ended up building one, it is a very well sounding amplifier.
Many many thanks to Nelson Pass for a very very good amplifier!
Oh, almost forgot to insert the pictures everyone probably wants to see.

Great thanks to Mr. Nelson Pass for sharing his knowledge.
OK, this is the simpest ZEN. For me it is a "trainnig project". J'm going to build next one. Which one???... J just think about it. New heatsink's I have already bought.

Well, as far as preamps go, here's my take on the B1, its evolved DC-coupled, wasteful-shunt-reg version 🙂
I hope that's worthy of being in this thread, where all the builds scare me 🙂

The board is available through Salas and Teabag here on the forums. Rcore looks like 30W from ebay. Nice build!
Hallo Aleph-X friends,
my new Aleph-X is ready.
I needed one year to build it. The magic eye shows the temperature of the heatsinks.
I use speaker protection pcbs to control the offset of each output against ground and switch the speaker outputs to ground if their is a high offset and immediately it switches the amp completely off. There is no relais in series of the signal path.
I start with 0,6V from each output to ground. Half an hour later you can measure under 100mV
This is only possible with a special thermal offset correction.
On my homepage you find a german description of the Amp and more pictures.
Maybe someone can translate it for the forum here. I think my english is not really good.

It sounds really incredible. I am very happy with ist.
I have to hear all my cds once again.
The bass precision is amazing. I did not think that this is possible with a Single Ended amp. the rest sounds like a good tube
I am not missing a Aleph 2, i am glad that i have built the Aleph-X.
All correct.
Check the group buy threads for the boards.
I can't remember the rating of the R-core, but it's a very nice transformer, bought from ebay. For a great price too.
