bmichels - sorry for my bad explanation - if the bottom side is where the battery is placed and the the amp is standing on i called the top side the small side that is on top.
so in your right picture if you rotate the volume knob 90 degrees left the knob is one the top small side as if this were the small front panel of the amp. and then left to the volume knob on the picturethe jacks.
so the amp gets as small as possible, but okay, i mentioned to use a new housing, the pcb of the tubes must be mounted in a way that you can swing up it to change tubes.
i really thought of rearranging the components in a small box to get it as portable as possible.
