Also try replacing the interconnect between the phono stage and amplifier. If you still get it, get an extension lead and see if you can plug the table in to another circuit. It sounds like it is definitely the table.Take the phono lead out of the amp and turn the amp on to see if you get the noise you mentioned when doing this. In your case then, the noise is being amplified.And the QED is dry cell powered. Generally at loud levels, you shouldnt be able to hear the noise. It's not a huge problem but one which I'd like to rectify.but at the moment (as I'm very poor), only if the solution is simple/cheap. Remember to run audio cables at right angles to the power cables, not parallel.Ĭan you hear the noise from your seated The same buzz happens with two other phono amps (Project Phono Box and QED Discsaver) that I have used with the same set up, so I don't believe it is the Vincent.and yes, I can hear the noise from my listening position but mainly because the volume setting is loud. When your hearing these problems, I assume you are putting your ear to the speaker. Borrow another phono pre amp and give it a whirl. When you are diagnosing these noises (As soon as the amp comes to life, a light buzz is evident and when the TT motor starts up, a light hum begins.) Where do you hear them from?Equipment also has quiescent noise, which can be the noise the components make in the circuit.You have had problems with the Vincent before. The only noise on the MC setting is a very light 'white noise'. Post edit: Another thing I just remembered is that the 'buzz' is only evident when on the MM setting on my phono amp.on MC it is absent. I really only hear them because my amp is usually (.always ?) set to LOUD! At 'normal/average' listening levels, they'd be hard to pick up. On all other sources (digital), the amp is dead silent. As soon as the amp comes to life, a light buzz is evident and when the TT motor starts up, a light hum begins. It's very satisfying when you are able to diagnose - and then fix - a problem. In my case I had the same level of noise if the power was plugged into the back of the turntable or not - so it had nothing to do with my power plug wart or electrical noise on the circuit. I also noticed on the back of my turntable that there are two little washers for the grounding wire to slot in between, I likely had not been slotting the ground wire in between these two washers - I can now crank my amp up super loud with no music playing and YAAAAAAS no buzzing sound. Turns out it was a really simply fix - I separated out the RCA Left and Right from the ground wire, ran them entirely separately, tightened everything up and made sure it was tight on the back of the turntable and the amp and it was magically gone. I read countless articles and various fixes on youtube and it drove me mad for many weeks. I finally fixed my grounding 'issue' (not a loop) yesterday with my Project Classic turntable. ![]()
