Enclosure arrangement
hi,
after one year on a wooden board now it's time to build a real enclosure for my FE. In the attached picture you can see how I would like to build it.
There are three areas: the leftmost one is shielded and dedicated to the trafos, middle area for input selector , an internal dac (subbu V3) a pot and a future relays/resistors board for volume attenuation.
The rightmost area is for the FE boards.
In this way, signal/audio and power supply lines shoud not cross.
I haven't drilled anything yet, so let me know if you see any disadvantage in this setup.
I'm a novice, so any suggestion is welcome!
Best regards,
Filippo

Good job, very promising. Especially i like the metallic shield between the transformers and the electronics. Two questions:
What do the little transformer feed?
Where did you purchase the heatsink?

Nice adequate heatsink for two 3886.
That will ensure the normal operating temperature is kept low.
Just make sure EVERY circuit has it's own Flow and Return Pair. AND that each pair are close coupled or better, throughout their WHOLE route.
Once all that is attended to then make the few extra connections to components that need a reference or Safety connection.

Hi Luigi,
the heatsink is part of the enclosure I bought from HiFi2000. It's a "Pesante Dissipante" model but i'm building different parts of the enclosure by myself: the left side and the shield for the transformers are not part of the original kit. I think they also sell the heathsink alone as spare part.
The small transformer is part of the power supply of the subbu DAC (the small rectangular board in the middle area)

My_Ref Fremen Edition Group Buy - 6th Run
Just in case you guys haven't heard, Dario has opened a new group buy for the FE boards. Naturally, it's located in the Group Buy Forum.
I'm in for another pair. That will make a total of 7 stereo pair, if memory serves. Three pair built and working, although I have some finishing to do.
I would be curious how many pairs of FE boards have been built and have amplified sound. So starting with my 3, add yours on and let's keep a running total. My guess is that it is more than 30.

Five boards successfully built. One not working board which I really must get sorted so that I can give the amp to my son.
Glad to hear the interest/demand is still growing. I've got two stereo pair (4 boards) running. Also boards and most parts for another pair yet to be built.
I have a pair that has been my daily use amp for nearly two years. This amp never fails to reveal the magic of a great recording.......and the shortcomings of poor ones. Thanks all.😀
That's 16 stereo pair up to now. I am counting those that are close to running. Still haven't heard from some names I remember from earlier forums. I still guess we have 30 total.
Keep up the good work. I agree with all those that have enjoyed them a lot.

I've got four FE monoblock amps running: a pair here and a pair on my friend's Eggleston's. They are all sounding mighty fine. Building a center channel single amp soon.
Going back to MyRef RevC, I've got a working pair of those and have destroyed another couple with excessive experimentation!
Mauro is my hero, Dario not far behind.
Peace,

Hello Myref_FE-friends!
I have a pair running smoothly since 2013 and another pair of boards empty (for the moment ;-) ).
Thank you to Dario and all the community!

Hello to everyone,I just thought I would share.I got this far about a year ago and haven't done anything to it since.It's hard to take apart once it's playing😱.
I can say this.It's the only thing in the house that I can play for extended periods of time at louder levels without the wife stomping over and turning it down.😀 I don't know what it is but man this thing is Sooooo easy on the ears.I have other lm3886 amps in the house but compared to this,they kinda make you wince after awhile and I end up turning off...much sooner.
I'm very happy I built it.
Thanks to you all
On top is a b1 buffer SALAS board that I've had for years and recently finished after getting inspired by the Myref freman.
