That looks good.I made this for three years. 🙂

Can
we have more details on your UGS ?
hi everbody!
I (proudly 😉) present my two F5 mono-blocks.
Since semptember 2011 I worked on them- it is too much to tell, but now they are ready to make some fascinating music for me.
The case is made from 10mm aluminium, which is anodized in non-glare black.
Heatsink is the back of the tower case, it was CNC-milled to fit all the in/ouputs.
It was really hard work, I learned much about programming and working on some atmega's and displays, current-measure-IC's and mechanical things.
The PCB's are from the diyaudio shop, and they are perfect!
I have to make some pics from inside, but in the moment its a little bit chaotic.
They sound sooooooo nice, I am speechless.
THANK YOU SO MUCH EVERBODY HERE, especially NELSON! (and thanks to martin from austria for all the emails and tips!) 😉
(and sorry for my bad english...)
cheers,
matthias

How did you do the cool displays? Is there a build thread?
hi everybody and thank you for your comments! 🙂
@NYCOne:
look at my thread here:
http://www.diyaudio.com/forums/pass-labs/198298-few-questions-about-f5-amplifier-3.html
😀
(the video shows only the first steps of programming. some big software bugs are gone now...)
the displays are from ebay. I bought them from a guy in poland.
nice price, very good quality and different colors, too.
the switches are from a case-modding-webshop somewhere in germany...
cheers,
matthias

hi!
its very simple: you need to put the ACS712 in series to R11, and another one in series to R12. then let the software doing the rest! 🙂
ACS712 delivers about 185mV per ampere. as you know, R11 and R12 are 0.47Ohm resistors, so it is easy to calculate the bias with the controller.
I did it all with bascomAVR, a nice basic-programming tool for the atmel µC-series. If you need any help, feel free to contact me.

Very well done, and what a unique build!
Do you have a photo of the back of the case? I am curious to see what the heatsinks look like.

hey!
ufff, only an old one, without the mainpower switch and the mains-connector. but with RCA and loudspeaker out.
I made it mirror-inverted, so the other case has got the connectors exactly on the other side of the backside of the heatsinks. (I inverted the amp-pcb and the capacitor-pcb, too 😉)

Realy nice ad on of bis settings and temperature and well evveriting
I wuld raly like to do the same on MY F5
Can you share/ post
I may even be interested in buy kit form if you make one

hi i am building my aleph 30
it is said this amp no need adjustment.
in my amp the dc at speaker out is 0 to 5mv on left, but always -22mv on right.
how to balance both amp?
thanks.

An externally hosted image should be here but it was not working when we last tested it.
And another one
Here is my Aleph J clone 😀😀😀.
Same look as my F5 😀 ->

But time all is DUAL MONO 😀.
All board are Point to Point wiring.
