How to hook up a tube preamp to my integrated amp

The technical side of music is not my strength so I'm looking for some help. I have a MuFi a308 integrated amp and want to hook up a Rogue 66 to use the phono stage for a Rega p25 with Benz Ace HO. The 308 has an AV pass thru and a Tape out. I was thinking that if I pluged the preamp into either of those they would work, but I don't want to screw something up with the amp or preamp. Any advice is helpful.

Thanks
