Hi, I am new to using turntables to play LP's. I recently found an old Technics SL-BD20 turntable in my basement. I wanted to try hooking it up to my home theater sound system, but I have run into some problems. I have a Sony STR-DE597 receiver that is configured to a 5.1 surround setup. My receiver does not have a phono input so I bought a pre-amplifier to do that job. Specifically the GE Pre-Amplifier AV23292. My turntable is inputted into the Pre-amp via RCA audio cables, and the pre-amp is outputted into my receiver. Specifically, the MD/Tape input. My problem is that when I connect these two devices through the pre-amp, a loud buzz is produced. The buzz clearly overpowers the LP Playback. If anyone knows what I might be doing wrong, and can find a possible solution to this problem, I would greatly appreciate it. Thanks.
You need to ground the table to the pre amp. If you've not done that, that alone should solve the problem. If the table is grounded, you probably need to ground the pre amp to the receiver.
