I received the boards, but was too busy with the new LM3886 stuff to assemble it and test it. Here are some initial photos:

I will build up the test unit soon. Everything seems to fit great.

Thanks! Nothing is decided for the end purpose of these boards. A kit might be sold by me, or maybe just Vikash. I don't know if I have time to put together an ship out another kit, as I do have a full time job, not leaving time to do too many kits There is a good chance that I would just be selling pcbs, while Vikash would be selling pcbs and kits with calibrated mics.

I will work on assembling the unit soon, along with mailing out some boards to Vikash for testing.

Jason, if you want one of the prototype boards, we can work something out. I also found the pair of SMD Mini-A boards when I was going through my boxes.

Drop me a mail and we can discuss this stuff. I forgot how small the miniA boards are (3"x2"), but I do remember how much heat they create

They should be available soon. I haven't had time to finish my prototype unit yet. I have a few prototype boards left if you are interested in one.

started assembly tonight. I got sidetracked with other things, and didn't finish, but I should be able to find time tomorrow night to finish assembly.

Here's a mic preamp I've just finished. I recorded a few choice sequences on my Tabla (drums) to test it, and it works great at both gain levels.

To begin with, I would like the kit to include the PCB and components, including switch and either two RCA sockets, or 1 RCA and 1 BNC (preferred), a mic capsule (or two), brass mic wand, and BNC connector plug (or RCA).

I have yet to assess the feasibility of having the mic capsules calibrated. At this stage I think it may be superfluous, and that the generic calibration file floating around will be fine (and free!).
