Any info about this amp? A friend of mine's got one of these, made in USA, and it hasn't any Celestion speaker but an Ampeg Special Designed one (or something like that) that sounds quite like a Celestion, but I think it's not the original one because it's supposed to be Celestion equiiped (there's a plastic label that afirms that). It seems it's a newer version of the SS-70, but I think it has the same circuitry (I've seen a guts pic and looks the same)
