yup.. basically what olaf said. i've still got my aor 50 watt combo with a 70 watt fane. i really do like this amp.. but you've got to mess with the tube compliment to get the most out of these. they're kind of picky. there's info out there.. but you've got to do some digging to find it. manuals can be found on the laney web site and schemactics are over at schematic heaven. you could also go over to plexi palace. tube getter is the resident aor guy.. but good luck getting him to divulge what he's using for tubes in his.
