I also built my Seduction as the Wardsweb's suggestion the transformer terminals face to opposite side. No problems at all.
I think it did make soldering work easier when I worked on rectifier components.
Have listened my Seduction almost 10 months, no hum at all after about 20 hours burned-in. I turn the volume to max only hear the tubes hiss.
I did make a newbie mistakes when I built my Seduction, and many thanks all the helps from Doc. B, PJ., and Grainger.
I'm very happy to have my Seduction, very good sounding.
