My Ampeg is a SVT 410 HLN. Aren't most of them SVT 410 HLF's? The spec's seem to be the same as the Ampeg site states for the HLF. Is this a typo on the back label or is the HLN an actual model? I just purchased it at Xmas, brand new. It's rated at 500 RMS watts/1000 program watts@4ohms. Where as the HLF is 400 RMS watts/800 program watts@4ohms. Ported cab, tilt back casters, same dimensions,etc. Just wondering. Anyone?
