You could get a Rotel RQ970 Phono Preamp. New list is $200, used between $100 to $130. They are Stereophile recommended. There are also very inexpensive Moving Magnet phono preamps that sell for $31 dutch auction on eBay. Do an item word search on eBay "Bozak". The Bozak Madison phono preamp stage may be all you need if you just want to play old records.
