I could make and informed decision thanks to you all. To say the least, this 18+9V business is over my head
I decided to replace the Alesis pre (the one needing 18V) with a M-audio dmp3, which needs the same 9VAc as the Art pres. Still 1A for 2 channels: no tubes in there, which is probably for the best...
I will take all your advisement into consideration, tracking ground loops and improving protection. At worst, in case I fail , the 2 Art pres will stay in the bag with their wall warts and the m-audio will have the 8A tranny for itself... Shouldn't run too hot

I'm doubtful about a dual tube pre at 68€ anyway...
