Good news, my CTH buildup using the new BoM & PCB from latest batch is working perfectly. We'll handle mundane payment & shipping biz in the IC thread: http://www.head-fi.org/t/581511/ic-cavalli-compact-tube-hybrid-cth-pcbs-rev-1-3-aka-rev-a , keeping this thread as its been for build info/assistance.
So we'll forward the new CTH Rev A XLS BoM for hosting on CTH Rev A website, it may be called something like CTHA....Dec2011.
I'll forward links to a shared Mouser BoM + Digikey parts #s with my request for PCB payment. You'll still want to make enclosure, pot, knob & jack choices at least, so carefully review things before pressing PLACE ORDER :) And you'll need the little mounting & wire bits external to the PCB.
Here's pics of my new PCB build up:
Only variations from the std BoM IIRC are V-R gray C4 box caps (had around) and 20mm height C10P & C5P (necessitated 1000uf -> 680uf) as my planned enclosure needs 20mm max component height.

The latest BoM raises the heater circuit L1H & L2H coils to the switcher's max current - 1A. This allows safe operation of tube heater draws up to 800ma, since anything > 600ma requires LM2595 to get a heatsink I've added one. Also, although entirely unnecessary, I've doubled up the 24V reg's heatsink (because my enclosure can support it & I've a thing for heatsinks:) Note the bottom 2 "teeth" of the inward-facing 24v reg heatsink have been cut off & the heater switcher heatsink is upside-down with it bottom segment snipped off. Both regulators have been soldered in as high as their leads allow, you'll need to let your enclosure fitment drive these details.
