It's still a work in progress... but it's getting there.

Dealing with certifications is not fun.

Slow and steady though, and I'm not quitting my day job!

Cheers,

yeah fair enough, thus my smileys, the comment of copying was more general, as I have previously been mistaken for someone who might have the gerbers for opcs amps and willing to give them away

The information posted in this thread is very deliberate in its content, and there's a good reason for it. I provided the schematic, BOM and an image of the layout in the first few posts which is everything an individual would need to build a completely DIY version of this amp at home, including the PCB.

There is a superb example of someone doing just that in the NTD1 thread. He took the time to size the images, etched his own boards, and the results look excellent, and probably function every bit as well as a production PCB.

I used to do that for many of my first projects, so I appreciate the amount of effort it takes, and I fully endorse people using the provided information to build their own amplifiers. It naturally self regulates since it's such a pain to do that nobody in their right mind would ever try to sell a finished product based on boards they etched at home.

As soon as I start sending out Gerbers, then I completely lose control of who makes boards, how many they make, what the quality is, and what circumstances they're sold under. I would be exceedingly upset to see one of my designs up for sale on ebay from a Chinese knock-off vendor for $2.

The basic message is, if you really want one of these you have three options:

1. Etch your own boards with the information provided here
2. Design and etch your own boards with the information here
3. Wait about 6 months and buy a beautiful completed production version

I know it would be possible to copy the layout pretty much exactly if you have access to layout tools, but I'm hoping the effort involved with that would be enough to dissuade people looking to blatantly rip-off the design with minimal effort.

If you want to do the above, then there's not a whole lot I can do to stop you, but I would ask that you limit distribution to a smaller run, and always give credit to the original design, while letting people know that they're actually getting a copy of it, and not the real thing. In this case in particular, I'm pretty sensitive about it since I'm currently pouring a good chunk of time and money into trying to make a go at a commercial offering.

I don't ever want to dissuade a DIY builder from doing their thing, which is why I shared the design in the first place, but I'd be pretty heartbroken if someone took advantage of that for financial gain.

Cheers,
Owen

I'm looking for some help with 'the wire' headphone amp. I haven't powered them up yet, because I can't get +/-12v out of my power supply.

I can ship the boards off for repair, or preferably if your in the greater Toronto area - I can drop them off.

Merlin, what problems are you having with the PSU board?

Don't be shy! Or have you just not got the time to finish them yourself?

I understand completely.
I will not be pursuing any involvement in a further run of boards.

Cheers!

I must be shorting something out on the psu board. I've removed the diodes a few times, and drop them back in and getting similar results.

I'll have to take a close look at them soon, ever time I've want to work on them I've got to clean the kitchen table.

Is it possible for you to post photos of both sides of the board? What outputs are you getting? Is one of the rails working and not the other perhaps?

I'll take a good look at it tonight, and report my findings tomorrow.

Thanks
