In 1975, I bought a Concert Lead head with a 412S Speaker Cabinet. At the time, I was lead to believe this was one of the the normal configurations. The Sunn Spec Sheet shows something different, but since I have no other information I cannot be sure one way or the other.
Anyway, I would like to sell it, but haven't a clue what the value of it might be. It still kicks with plenty of power, and is generally great shape (played through it yesterday to rattle the neighbors windows). I'd appreciate any feedback and/or serious offers.
