Update - solved by switching input to tape 1 and turning on built in preamp!

My audiophile uncle passed recently and handed me down his awesome McIntosh set up from around 1970. That being said, all of this is new to me and I have never had vintage audio equipment before.

I got it all serviced and it is sounding great with the Wiim streamer. However, when try and use the turntable (Pro-Ject Debut III Phono SB) there is a low hum or buzz noise. I have tried using the switch to bypass the built in preamp but it is still buzzing. I have also tried different RCA cables with different styles of grounding wires but no luck.

Any ideas to fix this? Do I need to buy a new turntable that is more compatible?

Thanks y’all!
