Actually, I assume that was you that just posted on the Unisolder forum about this too. Ironically, the non-toroidal one he listed specifically is 144w, when he's saying 130w... Doesn't seem to specifically need 130w, but I also don't know how far over 130w the unit will tolerate. An extra 30w is 23% over recommendations. You could go with the Hammond 1182P12 which is 120w, to be on the safe side. I was going to get a unisolder, but I couldn't get into the forum, and I PMed him here, but never got an answer.
