Ground loop b/w amp and phono stage
But when I used the CD player, there is no buzz at all. It's only there on the input which the phono is connected to.Not a ground loop jmho.... Do you have the TT grounded to the phono preamp? What happens if you disconnect the TT from the preamp and install shorting plugs on the phono preamp inputs? |
, if I do that, there is no sound.No buzz you mean? Complete silence? I tried an rca cable plugged into the input section of the phono stage though (Kent at Pass Labs asked me to this) and the buzz returned.An open ended patch cord connected to the input of the phono preamp sure would cause a buzz... I think you misunderstood what Kent at Pass Lab wanted you to do. Or I am misunderstanding what you did... Just for the heck of it did you try connecting the ground wire from the TT to the Ayon Triton integrated amp instead of the phono preamp? |
Ssayeed, By chance did you try lifting the signal ground from the amp's chassis with the toggle ground lift switch on the back panel? http://www.stereomojo.com/Ayon%20Triton%20Integarted%20Amp%20Review/AyonTritonIntegratedTubeAmpReview.htm |
I ended up borrowing an Aesthetix Rhea and the problem persisted. Any ideas? Try another set of line input jacks on the integrated amp. Try another pair of ICs from the phono preamp to the integrated amp. Make sure the plugs are seated all the way in the jacks. Same process for the TT if plug and ICs connected. Hook up another TT to the phono preamp. Maybe borrow one.... or go to Best buys or equivalent and buy a cheapo for a test. If you have a B&M dealer in your area take your TT to them and have them connect it to a system of theirs... |
If I do not connect the ground wire to the phono stage, the sound is reduced but it is still there. Any more ideas? Ssayeed, Did you try to connect the ground to the chassis of the integrated amp? Maybe a screw on the bottom of the amp. Have you check for proper AC polarity orientation? Sometimes that can cause a buzz. Maybe the amp is crossed.... http://www.boundforsound.com/tweak.htm http://www.gcaudio.com/resources/howtos/acpolarity.html and then there is this. http://www.jensen-transformers.com/an/an004.pdf http://www.jensen-transformers.com/an/generic%20seminar.pdf Just grabbing at straws..... Have you tried unplugging the TT from the AC power receptacle and checked for buzz? |
