Since your main goal is to upgrade your vinyl playback, maybe you should keep the 911A and get a turntable and phono stage (Cambridge 640P or Musical Fidelity V-LPS) and plug it into the Aux input. You could still use the built-in Garrard to play 78s if any come your way. Other than the rolloff in bass power (that's about 2.5 dB down from the midrange peak power) it's a nice unit--clean, smooth, and as I said, great tuner.
Do you have the 887A speakers that came with it? If not, what speakers are you using with it? One year in college I powered a pair of Altec 9845As with the 911A unit with good results. It's the battleship grey monitor at the front right in the picture. I was in a music group that used a pair for our PA system and we "stored" them in my dorm room when not gigging. When we disbanded we sold them to a theater. That's how much output they had.
