Hello everybody,

Wich lm3886 stereo kit or bare PCB can you recommend ?

Modulus 86 boards seems interresting, but too expensive IMHO.

Hi P....,
Modulus 86 is a very good way, maybe the best way for LM..
Cheaper, kit from Chipamp.com :
LM3886 "fullrange"

Having built one of the X-Y ebay kits, I can say that they do indeed function, and I'm pretty happy with the sound. There are probably 1000's of posts on the board about this.

In hind sight, I think I would have rather gone for the chipamp.com kit mentioned above as after all my readings, I think the PS board is better.

YMMV as they say on the boards.

Dave

My speakers are still the Nomex 164 from TG.

I'm planning to build the Elsinore from Joe Rasmussen this summer, a kind of upgrade

Best regards,

Pascal

Hi Pascal,
LM3886 "fullrange" will be fine with the Elsinore, it can get about 55 watts..
Total cost is between 200/300 euros, depends of quality of case, connectors and so.
Two guys built this amp with sucess, and I can help you to find components.
Regards.
Phil.

Hi Pascal,

If you are going to build Joe's speakers..... then his "current" amplifier would be the logical or even the only choice....

I have a First Watt F1J current amp and it's just amazing.... my speakers are REF3A Episode and it works superbly with them. I will not change my amp....ever...

regards

Hi,
I don't knaw nothing about Joe Rasmussen "Trans-Amp", but it use LM3875, basically 3875 don't works with 4 Ohm load, except with very low power and low distorsion..
What power with Trans-Amp in 4 ohm load ?
Phil.
