Is my amp available with a hardwood cabinet, like cherry or walnut?
No, but you can certainly go to your local lumber yard and pick up a piece of any wood you like, 4/4 S3S or S4S. This means the wood started out 4/4″ thick before it was Surfaced on 3 or all 4 sides, and it winds up more or less 3/4″ thick. Use the templates to measure the size of the top-and-bottom, and cut your new pieces exactly that size. Next, stack two pieces of kit poplar next to two pieces of your hardwood. Are they exactly the same thickness? If your hardwood stacks THICKER, you will have to cut the SIDE pieces LONGER by the same amount! If your hardwood stacks THINNER, you will have to cut your SIDES that much SHORTER! Now when you use the templates to mark holes on the SIDES, line up the template to the front edge and one end; mark the holes and adjust the template to line up with the other end. Piece of cake.
