Possibly. I'll be giving them a call Monday, hopefully I'll find something out

I wonder too, but what could make me the culprit? When I brought it into Sound Advice today one of their experts set everything up and nothing was different. Also I tested the cart leads for continuity with a multimeter and they're all correct. Touching the arm or cart screws change the hum.

I've used different cables for grounding, unless you mean internally in which case I'd wonder why I've seen 3 Debut Carbons with that same grounding issue with no widespread complaints online currently

Cambridge Audio Azur 651P (replacement for Bellari I thought was the culprit) -> Tannoy 501A Powered Monitors (I've tried other speakers, receivers etc. to no avail). I don't usually use strips or conditioners but have tried both in the troubleshooting process and nothing helped. I've really run the gamut trying to figure this out but i'm certain its the Debut at this point, and just wanted to know if there was any way to get this one working or have better luck in getting a working one.

I had a post a little while ago about a strong hum in my setup. Long story short, I went crazy trying to find the cause of this hum, and finally found after bringing my TT to an audio store and using it on their equipment that this Debut Carbon is the root of the problem. It is also the brand new replacement I got after the first Debut Carbon I bought around Christmas had the same problem after being fine for the first few days I owned it. I do want the Debut Carbon to be my TT but don't know what to do. It is the updated DC model so I'm confused as to why it is even having this problem in the first place. I'd send for a replacement, but I've already done that and both units have had the same issue. Any advice?

I have a Bellari VP 130 but was thinking of maybe exchanging it if there were something better in the price range. If the pre did not have an output control I'd also probably end up wanting to invest in a separate volume control, since I'm using powered monitors with individually knobs. Thanks for any and all suggestions

Its a ProJect Debut Carbon DC

Also, the problem persisted somewhat when I tried the TT with a stereo receiver I have. Could it be a TT issue? I noticed the hum changed when I was touching one of the cartridge screws.

Gotcha, it wasn't really a good idea in retrospect. But now I've ditched the weird screw thing all together and am noticing the hum that wasn't there before. I wouldn't think I could've damaged my system that bad just from hooking a wire from the ground screw to a metal screw, but am I wrong about that?

Sorry I didn't word it well. I've heard people say they've fixed hums and such by taking a speaker cable from their setup to something like plumbing to divert any extra electricity as a final grounding point. I basically connected the ground screw on my preamp to a screw in the wall of my house as a ground. Is that a bit more coherent?

My VP130 was working fine in my setup for the most part, but yesterday I was fiddling with my setup to try to get rid of some static. I connected the ground screw of my pre to a ground screw on my house, but after finding that didn't help, I decided to remove the speaker wire I used to do that. Now there is a loud hum that won't go away unless I hook that extra ground back up, and even still it is still more noticeable than before. My turntable is properly grounded to the pre like it used to be before this issue arose so I don't understand what went wrong. Any advice?
