Seems to be a pretty nice little amp and it was exellently priced at $0.00. I cleaned the pots and switches and hooked it up to the Altec 416/ Heil AMTs and it really rocks! Pink seems to really mean it when she sings that she has been a bad, bad girl. 3500 mean it is 35 wpc? Not that I can turn it up very far with these speakers without damaging my ears.
