Here's my entry.  Just finished the cabs last night.  Ported speaker cab, based off the TL806 plan, houses an EV12L.  Suede all around.  Probably would have been cheaper, factoring in my time,  to just buy the cabs and cover them to my tastes but, there is a great sense of satisfaction having done my own work.  Oh yeah, very nice amp.  I still have some minor tweaking to do but, I'm definitely in the ballpark.
