Sorry for the long delay. I have been really busy. I just finished buying my first house last week, and have been busy with this and mailing out LM3875 kits over the last couple of months. I have the board files ready to go for ordering prototypes, and haven't mailed them out yet. I will do this very soon, and once I verify that the boards work good, I will order the production boards. Another reason for the delay is that I had been planning to submit the board files for both the tda1543 dac and LM4780 at the same time, and got delayed with that project as well.
I will try hard to make these kits a reality soon.

No, those DACs are not kits yet, and I have serious doubts if they ever become kits, seeing the current attitude from certain forum members.
I developed that DAC over a period of one year and lots of tweaking went into final design. The components layout has been finalized, and the whole thing fits into 2 x 3 aluminum tubing as enclosure. I'm still uncertan about grounds layout, that's why we decided, with Brian, to go with 3 diffferent versions and compare which one is best.
Recently I had a chance to listen to AckdAck, and my prototype, although run from AC, was a fair contender (actually was preferred by the guy who brought me the AckdAck for comparison).

Interesting Peter! Keep up the good work ;-)
I also have plans to design a small DAC pcb. I want to try some ideas I have. Though I am not yet sure if it will ever see the light...

Hey Brian,
are you going to have battery powered dac kit version?
how's the performance for the gc lm3870 with the zobel? any chance i can get an upgrade deal (instead of the entire kit) only need the newer pcb and the resistor + cap for the zobel. i have the first gc kits.

As for the dac, I have no solid plans to offer kits at this time. I will work with Peter and see how the prototypes work out. I also wouldn't want to upset Scott Nixon and offer a cheaper kit...
As for the LM3875 boards: Sure, this is possible. Drop me an e-mail. I will include the zobel components for free, along with the pcb set. The resistor will be a 3w resistor, as seen in the picture here:
http://www.diyaudio.com/forums/showthread.php?postid=439711#post439711
so it won't fit the spacing, but it seems fine as it is in the picture of my board that I posted. In the future, I will offer the components as an upgrade to the kits, along with the 2w resistor.
As for the zobel performance, I am in the process of moving now, so I won't be able to do some comparisons for a couple of weeks, after I get settled in.
As for the LM4780 boards, I still haven't ordered them, but will work on it soon. I have been extremely busy with my job, shipping out the LM3875 kits, and I also just finished buying my first house, which has taken up a lot of my time over the last 2 months. I am moving into the house this weekend, so once I get settled in, I will start working on making this project a reality. house pics

Nice house.
Doesn't need any work at all.
Here's a little bit of advice for marital bliss. Don't sail any week long regattas during the moving days.
Please get back to 4780 and the DAC. 🙂
Congratulations!

No GC in the house?
Brian-
DOAH! When I moved into this house I set up my walkman with my Cambridge SoundWorks PC speakers for music while I worked.
I expect to see picture of a Gainclone set up before ANYTHING is moved in.....
Of course I moved us in while my wife stayed back and closed the sale on the old house. Be happy if she lets you have a "space" for your audio stuff.

Edit: Oh and congrats on the new place. I think she would appreciate photo 87 being removed. The cheek rub(?) looks misleading. 🙂

hey brian,
your house is spaced out so you can play your music without disturbing your neighbors. or is it your neighbor disturbing your music. haha
what's with dac=scott? nevermind jk

Brian,
Congratulation on the new house. Are all those pictures of one house? I counted - there are more than 10 bedrooms!
By the way, what City and State do you live in? Somewhere on the East Coast? I'm not used to seeing houses with no fence.

Just north of Atlanta, GA. I don't see too many fences around here. The subdivision was started in 1997 for the phase I, and they are doing phase II now, with a few houses left.
For the house, there is one pretty big master bedroom (with the tray ceiling), and then 3 small bedrooms, once which I will make my office.
The basement will be my long term project, providing all the room that I need for my audio projects. 🙂
Anyway, got to get back to packing. I have a good deal of the small stuff moved already, and am renting a moving truck tomorrow for the big stuff.

LM4780
Brian.....I'd be interested in at least one 4780 kit. I've built one of Rod Elliot's 3786 'Clones, and am putting together final touches on his P3A amp. Two solder bridges, an unsoldered leg on a component, and six blown fuses later, I've got replacement drivers on order and I'm ready to make it play.
I want to get my son Ben and some of his 4-H companions started on some diy projects. Your Gainclone kit would probably be perfect, due to your excellent website instruction.
Please let me know when the 4780's will be ready. My PayPal account is waiting! 😀

Re: Re: No GC in the house?
I actually let my friend borrow my Seas Thor TL speakers, and my gainclones for a week or so, while I am moving in. It will keep me from getting distracted with projects. I might hook up my other speakers and my old leach amp, which I still have here.
As for my first task, I am going to have to finish painting the inside of the house, as the previous owner painted all the walls an awful pink color. I have 2 bedrooms masked off, and ready to go, and another room painted. The hardest part will be painting the room with the 20+ ft tall ceilings, which painters quoted me $1500 to just paint the 2 areas with the tall ceilings (http://sites.darg.net/mere/House/house_059). I found a friend who would let me borrow scaffolding for free, and my parents found me a $500 pickup truck (late 80s ford f150), so I figured that I would try to do it myself 🙂 It will cost me about the same, including the pickup truck and 6 months insurance, which will help me out with my other projects.

First thing I thought... that house needs some color! You painting it all boring white(ish)?
Congrats on the purchase though. You have kids to fill up all those rooms?!
