Will do. The 4th guitar on the list is mine (provided it dosent get bumped back by more orders) I also need to free up the CNC so I can cut out my chassis, or use one of the mills at my day job.
Thanks for the encouragement.
There will also be a video of the 2 guitara we are building at this moment, but it will probably be recorded with amplitube so not entirely revalent to 18 watt.com

I noticed this a while back, but forgot to mention it. If you look up the data sheet for the Z729 (which is GEC-MOV talk for EF86),
http://www.mif.pg.gda.pl/homepages/fran ... 29_GEC.pdf" onclick="window.open(this.href);return false;
there is a section on af operation with lots of handy hints on how to minimise hum and microphony. Particularly, you will find there is a sentence suggesting that connecting the screen to ground via a paper capacitor of at least 0.1uF stops a lot of noise.
Worth a read.
