Turntable Hum Issue.

Yesterday my system developed a hum when playing vinyl records. Not the standard 60 HZ hum or buzz but a sort of resonating hum or howl around 120 HZ. Nothing with the system has changed in years which makes this more difficult to troubleshoot. Yesterday I played a recent garage sale find record and around 45 or greater on the volume level the hum appeared. I can replicate the sound by resting the stylus on the record and tapping the turntable base and/or tapping the console that it sits on. Otherwise, dead quiet. Other records I have had for years are now doing the same thing.

Set up is: VPI Classic table with an Audio Technica OC9XSL Moving Coil Cartridge with 2 Grams Tracking Force. Preamp is a McIntosh C49 using built in Phono Preamp. A picture of the console it sits on should be in my System Profile. House is hardwood floor and built in the 1940’s. I have no idea where to start. I was thinking on moving to a Moving Magnet Cartridge. Perhaps less gain might help the problem. With that said, what is a good middle of the road MM Cart around $500 give or take a bit?

I still would like to solve the root cause as I do kind of like that Cartridge. I thought the VPI table was heavy enough to isolate that type of issue that is why I purchased it. Feet, isolators, etc… did not work in the past with other tables.
