I have loaned my working amp to a friend to get his listening impressions.
There were 10 boards. I built 1, I gave away 3.
Nebby has asked me for a board, I told him he can have one as long as he really intends to build it. Not that I have any reason to think that he won't, but obviously, at this stage, the more amps working out there in the wild, the better from the point of view of getting some feedback.
I want to keep 3 boards.
I will give away another 2 to the first responders to this thread who will undertake to build them in the next couple of weeks.
In about 3 weeks (hopefully) I will respin the board on the basis of what has been learned, (about the ground plane, if nothing else). Realistically, most people will take a couple of weeks to get the components.
I can't continue to give away boards ad infinitum, at some point I will be obliged to set up a facility to take payment. If people like the amp I may supply a semi-kit or even complete amplifiers.
The intent with this board is to produce an integrated amp in a small, off-the-shelf case and which will run off a wallwart. There's no reason, however, why the board can't be installed in a larger case and flying leads used to permit the connection of any attenuator or connector the builder wishes.
Both Avro_Arrow and I have shown some designs for PCBs using the LME49600 in a simpler stand-alone amp earlier in the thread. Perhaps you would find one of them more suitable, but you'll have to push to get something done, there's a lot of demand on our attention ATM.
