Peter, well done!

To be honest, I can understand some of the sentiments on pricing. But, having tried this route also once, I KNOW how much effort and money you need to put in, before having the foggiest idea that you get anything back. Then, if the train starts rolling in earnest, so will your expenses!

In that light, I think the price is entirely reasonable, and I hope you sell a ton of it. Looking forward to your next creation.

Congrats, Peter! A beautiful implementation, as usual. Obviously, it works (I read the review)! I wish you the best of luck. I hope you sell all you care to build!

Default There's a man with a soldering iron in his hand!

Peter,

You may already cover this but I do not think it will hurt for me to mention it here I hope. Regarding the warranty that AMP-1 provide how do you ensure there is no denied lose soldering iron at work and return to you after the warranty coverage to clean up or replace then faulty parts(expensive ones)?

again congrates

Chris

Do you mean that there might be a loose solder joint after 10 years, and then what happens?

Currently I'm doing soldering myself and after first applying solder, I wet all joints with reisin and resolder again. This provides not only for a better looking job, but also more reliable.

We were also thinking about mounting 2 spare chips on a front panel (on the inside), so in case someone needs a chip replaced after few years, they would be still available (inside the amp)

I would not do that. Just save enough chips in a locker for repairs. Buy them in large quantities. Most people will not need a repair, so the two chips are wasted in that case. Though the advantage is that you can repair with chips from the same production line (and moment).

Chances are very good that there will never be a problem, as long as it is soldered well in the first place. Have you ever tried soldering up an assembly with the chip/resistors/caps and potting it in epoxy? It would guarantee that you would not have a broken lead in the future, and would also damp out resonances in the assembly.
