The amp I am keeping is made out of inch thick quartered oak. It is not quite as tall as the two stock cabinets stacked. The neat thing is, there is a guy on Ebay who sells the solid copper plate in exactly the size I wanted. I think the normal plate is six by eleven inches (I do not have one here to measure), the front and back plates are four inches square and you definitely need a taller cabinet for those to look right. My son has very specific tastes and lots of black furniture so I knew I would be doing laquer on his and I already had the two stock cabinets laying around. I do believe Bottlehead sells them as such if you ever want to go that route. I will be building two more and at least one will be polished copper with the quartered oak for which I was offered four figures so I really need to take my time on that one.
