Finally completed the S3X.

Rust oleum gold, wood stain and a polyurethane gloss finish.

I've only just learnt that poly off gasses for about a month so I'll have to move it out of my bedroom for a bit.

It's had about 65 hours on it vanilla and another 15 with the C4S. Some might pick out that the LEDs aren't upside down on the C4S board but trust me, I'm a professional I quadruple checked polarity when building it and it didn't explode lights up and works.

Time to hunt down a volume pot upgrade and possibly some interstage and parafeed caps. Any suggestions?

It definitely shows that you took your time on the build.

Really nice, great job! The only changes I've made to my S3X are:

1. Installed Audio Note pot from the beginning.
2. Installed a 4 pin XLR headphone jack.
3. Opposing diodes on IEC socket ground.

I am going to leave it as is because it sounds perfect.

Thanks guys, it was a great experience building the thing and I'm already looking forward to my next one whenever that may be. I was using this old SEPP tube amp till I made this kit and the S3X has definitely blown me away. It really makes my LCD-2s sing and with plenty of power to spare.

Did you have any issues mounting the Audio Note pot? Looking at the data sheet, it doesn't look like it has the alignment pin in it like the default one has that locks into the groove.

No issues but it takes a little work, easy stuff. I believe the plate hole needs to be enlarged (drilled out) slightly (can't remember). Then I used a washer on the bottom side and cut off 1/8 inch of pot shaft so my volume knob fit a perfect distance from the plate. The pot nut was just tightened down good and it has no chance of spinning unless the knob it aggressively turned which I never do.

The photos show the pot on my Crack but it's identical mounting to the one on my S3X.
