Hello! I´ve bought an AMP BH-420 from ebay (200EURO). It hasn´t arrived yet, but it is obviously in mint condition. Because there is little info about it on the Web and in this forum, I am interested in how much you can tell me about it. A manual or schematics via pmail would be superb, but i´m not that optimistic . I will let you know for sure what I think about this amp... Thanks a lot!
