Great find. Nothing beats the sounds of an Ampeg all-tube head, especially when using it with the Ampeg cabinet designed for it. My rehearsal rig is a '69 B25B head and a mid 1970s B25B 2x15 cabinet. I love the sound and its hard to not gig with it. But the cabinet is just too big for me to haul around, considering I'm also carrying at least half the PA system. But I get to enjoy it once a week for two or three hours.
