Had a friend that played in a local metal band back in the '80's....he was handy and purchased a beat up old Peavey Renown (130w I think?) combo...built a head enclosure for the amp itself, then 3ea 2x12 cabs (can't remember what speakers he used), and it was one of the best sounding amps I'd ever heard! I love my valve amps, but that thing was amazing!
