With Guinevere, I've been putting a lot of thought into the aesthetics. You're right about looks; it makes all the difference. When the pre and amps are done, I plan on this being a showcase item for the house. Our neighborhood is really into in-home entertaining, and I want to show this off in the worst way. I have a place in the hearth room already picked out - just don't tell my wife I got the base done last night. It is 4 pieces, joined with miter cuts, of pretty elaborate base/shoe moulding combo that we used in the kitchen in place of the standard toe kick. I got the copper top cut last week. One good thing about working with copper is that it can be scored and cut with a sharp utility knife. So, making a transformer cover out of "+" shaped piece, as in your kit, from copper seems to be a pretty attractive option. Again, I'm curious how it bends and seams. I know from expereice this is not a trivial thing to pull off and have it look right - you only get one shot per bend, and you have eight.
Please keep us posted on how it's coming......Colin
