Well I purchased a Pro-ject Debut Carbon after scouring the net for threads like this. I bought a demo online, waited for the delivery, powered it up andÂ…it doesn't spin. The power switch doesn't seem defective as I get a hum when I lightly touch the motor spindle, but it won't turn, major bummer! I was more than a little surprised that a major online dealer of Pro-ject would ship an obvious customer return unit without basic testing to see if the damn thing works!
Anyway, a BNIB unit is on the way. I've read about the Rega and Pro-ject entry level models having some occasional hum issues, but the Pro-ject seems to have a simple enough fix that's making its way around the net. But on top of that, my defective model's power supply seemed to be an issue. It's a wall wart that supposedly takes 120 VAC and steps it down to 15 VAC. This one measured 18.2 VAC when receiving 117.3 from my wall.
Would that over voltage be a possible source of hum issues?
