Over the top!! Wonderful case and implementation! So why try both LM3886 and LM3875? Is one for a sub or whats the deal

In fact I started with one Brian ( thanks to him ) LM3875 stereo kit, my first chipamp try to validate the quality of such a device on my DIY vifa loudspeeker (see http://crazyfrog.perso.sfr.fr ). Then I added two stereo LM3886 for a complete 6.0 amp system for hometheater:
- one LM3875 stereo kit for surround( side box heatsink )
- one LM3886 stereo kit for front (2 zalman)
- the last LM3886 stereo kit for center (1 zalman ) ... and backup if something fails.

It was a hard work to fill 3 stereo chipamp kits in a 8x50x35 cm slim case!! It works fine since 2005.

My XLS10" sub ( concrete case ) is not driven with gainclone, but a hypex DS1.2.

 

[huseying]

lovely case!
I really like the case you built.

Nice design, thanks for sharing.

Nice job.

Wow those rf chokes are HUGE!
What are they wound around?

hi there northernsky where did you get your enclosures from?

hi there northernsky where did you get your enclosures from?

I got the enclosures here with the optional aluminium front panel 1cm thick (it is much more beuatiful) but you cannot connect pot and selectors directly to the panel.

I got knobs here ,
they perfectly match the front panel color.

Hi,

I would suggest you to contact by email the online shop, maybe it is just that until now the shop never received an order from your country. I do not see any difference shipping to your country rather than another one
