Default LME49830 PCBs...

So I actually started this project a few months ago but to personal circumstances I decided to not continue with the project. Since them I have had quite a few PMs regarding the PCBs so just lately I have designed a new board which I have got made and will be testing tomorrow evening. After I received the boards I noticed a few niggles which needed ironing out and after playing around tomorrow to finalize values and layout I will get the latest revision made and if all good then I will get 100 made and sell however many people want on here then keep whatever's left.

Here is the latest PCB and schematic (with two pairs of ALF16N16W/P type). Estimated power should be around the 400Wrms mark into 8R and 4R depending on how you set your PSU up.

Intended heatsink http://uk.farnell.com/ohmite/ra-t2x-...Ntt=RA-T2X-25E.

I'm definately interested in 4 and maybe as many 6 boards.

I was considering building an amp based on lme49830, but this looks like all the hard work has been done. nice layout.

Any idea of pricing yet?

Wow, this is a very interesting project, and a very compact layout. I've been looking for a simple and compact amp board that has good THD above 1kHz, and this has the potential to fit that requirement nicely.

Looking forward to hearing the results of the proto board testing...

In any case, I would be interested in a dozen (12) of the final boards.

Also, is any one else interested in purchasing populated boards from an assembly company? I am not looking forward to smd soldering...
