My switches and switch caps finally arrived from Mouser.

I ordered this pn for the caps: 80180-2000

It is a perfect fit for the original switches, slides right on.

But, the switch I ordered for a replacement fit OK, but the actuator part was a little larger, switch was pn 1301.9319.24.
Also the leads were a little off, but I made little solder bridges, and it soldered down OK.

Fortunately, a size 1/8” drill made the hole in the cap a little larger, and then the cap fit this switch.

I just hot glued the switch board down, as shown in the pics below. With the hole size I used, the board kind of clicks into a spot where it is centered and positioned just right.
I know it looks ugly inside, but from the front it looks fine.

I am happy with this project. I like the way my chassis looks, although I still want to paint the top cover. The front came out nicely (IMHO), and everything fits fine. And I am pleased with the sound, currently using a zapfilter2 for the output stage.

My one complaint is that switches feel a little flimsy. I may be sensitive to this because I broke one already. In hindsight, I could have got five better qualitiy panel mount switches, and just wired them to the display board.
I could also have mounted the switch board a little higher, so the buttons would not stick out so much. But the switches work fine, so these are minor nits.

I did order some output transformers to try, and will see if I think they sound better.

For input power, I used three separate transformers, one for the zapfilter (it came with this), and two for the dac end. Each of these is 6.3V, 2A. Inside my dac, there is a AC filter network in front of each tx, to feed them clean power.

Nice job

LL1684 output stage

Only a photo of my actual environment.

Quanghao and me are testing a new solid state output stage with no feedback and probably this will be available like an option.

Hello Quanghao, Sorry for late to sent my remaining payment,now I want to ask the "The Kit IV stage" can order one again?(I mean I want to buy another one "The Kit IV stage" ) Have I a chance?
Thank you.

How is this solid state output stage different from the Kit IV Stage?
Could you elaborate a little bit and would it be possible to interchange those stages before shipping?
Thanks.

Erlend Sæterdal · 2013-06-20 12:00 pm

Does it require new shunts ?

We are still designing the pcb for this output stage so it will be send later.
In any case I think that Quanghao can give a special price for the first persons of this group buy.

Welcome to you!

The installation of the DAC has several difficult and strenuous for many of you, and choice of input connections.
So, I did this to help you, so hope you respond and give me ideas, Thank you

I will be assembling, finishing and inspection include the following:

1. All Input and output connectors
2. 4 x opam 2134 for IV
3. installation of parts, inspection and finishing
4. one year warranty for all finished products
5. shipped to you.

Your job: pay me $ 150 for installation costs,
and freight (if you have not already paid), to receive it and enjoy the music.

What is the "completed registration DAC"? If it is payment for complete DAC ($150), I have already paid.

Hey axeexa,
in a Group Buy thread, a basic principle is to update purchase/status lists.
By failing to update the latest list, you just erased the updates by 8 other forum members.
Might be a good idea to fix.
