Must be cold. Very cold. Not like the English warm beer - terrible.

I've put the complete Gerbers and drill files for these amplifiers up on my website hifisonix.com: Audio Amplifer Design and Music Reviews. If you want to make 'em, everything is there - look under the respective amplifier posts.

Any questions, feel free to ask me

:cool:

Just finished reading the NX amp documentation... seems like a tempting proposition, I am surprised nobody has jumped at the offer yet! I know I would be interested in giving the NX a try. Anyone else?

PMI,

I had high hopes of selling boards via a web shop, but too busy at work for now and at least the next 6-12 months - many projects. Quite a few people PM'd me asking for boards, so that's why I put them up. Please feel free to do a group buy. Same for sx-Amp.

Bonzai,
It is not only beer, they love flat beer as well, (homebrew it doesn't even have bubbles) Sorry guy's ' no bad feelings and they do not like ice with their Whiskey( Whisky) for the Scottish. Thankfully if works differently in Africa ! :D

I can give it a shot, since I am ordering boards in small q. anyway, both for this hobby, and some unrelated reasons, but TBH, someone would have to help a bit.

The most obvious questions would be which board or boards to start with. I noticed that the nx Amp has a few surface mounted parts on the bottom side, and that tends to discourage people from wanting to solder them. Others have solved that by having those parts professionally assembled, but that raises the cost somewhat. Making bare boards is very inexpensive, but any time a small-ish quantity goes into assembly with SMDs, the cost rises.

I had a few boards made for the through-hole version of the VSSA (details in the Pee-Cee-Bee thread), and those turned out to be about $10 each double-sided with solder mask and silk in quantity of a dozen-or-so. Q. 100, probably half that, not sure.

So, some discussion would be in order, regardless of who decides to take it on.

To anyone else reading this - This is a very generous offer, and it would be a shame to let it pass!

PMI, the SMD parts are really easy to put down - you just need a pair of fine tipped tweezers and a fine tipped soldering iron.

Dead easy - no kidding.

Agreed, and I have a couple of those, but it is something that will come up, I think... ;)

Thanks Mooly!

NX Amp Gerbers
 
There are some files in the Zip that I can't identify, or, just can't open in my free viewer.

I can display and id the copper layers, silk screen, board outline, solder mask etc., but not every file. It would help to have a reference w. the file name please.

Outside dimensions look close to 98x110 mm?

Bonsai 3rd June 2013 10:59 PM

PMI,

Ok, I will sort that out for you later today my time.

Re outside dims, yes that is correct.
