Well, I've managed to get my Box-O-Trix built just in time for the UK 
SDIY get-together :)

Pics are up here if anyone wants to take a peek..

Info on how I made the panels is here:

I did come across a mistake on the PCB - the JFETs Q1, Q2, Q3, Q4, Q5, 
Q6 are shown the wrong way round (just goes to show you can't trust the 
libraries that come with your PCB software!).  I've included a note 
about this on the Construction guide page.

Apologies to Louis and anyone else who's already stuffed the PCB.  
You're going to have to rotate those JFETs, and if you've already found 
the values for R110, R111, R112, R125, R126, R127 you'll have to change 
some or all of those too.  Incidentally I found that the panel controls 
need to be connected when determining which values to use for these 
resistors.  If it's all a bit of a hassle to find the right values then 
just use 30K for all and should be ok.  Full info is on the Construction 
guide page.

See some of you on the weekend :)
