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

Thanks for your responses and ideas. While all the solutions in all three posts will not destroy my components it seems like the last is most appealing, since I am interested in how my CDP will also sound through the tubes of the Rogue. Thanks again.
Revdeg,

You are welcome! It's nice to get a "Thank You" every once in a while!

Enjoy,

FYI- Received the Rogue 66 and hooked up the phono through the AV through- it's exactly what I was hoping to accomplish. Sounds great, now I want a new amp:(

Thanks all for the posts
