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.

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.
