Sat down to listen to some music ten minutes ago and no sound on the right channel. Swapped everything, still no right.
Changed speakers and its fine. This means that its one of the Quads. This does not make me very happy.
Any guidance for likely cause please. There is no sound at all so I assume its a power supply thing rather than a panel problem.

I assume you checked the power light is on? Indeed, swapped the power leads over as well, just in case. The light is flickering but its been doing that for some time. |

Yep, they did that on mine, it's a neon light I think.
not much more to suggest except opening them up, assuming you are comfortable doing that.

Well, I can open them up OK but then I'm stuck  However, I think I know a man that may well know what he's looking at so I will just have to be patient and listen to the Teufels for a bit. Not the same though. Thanks for the suggestion Jammy but I leave the Brummy screwdrivers to the Brumegans  |

Aye, Alan would be your man. He's in the UK right now but will be staying here during the Circuit de Remparts weekend in Angouleme. He might get to see some of the cars if he's lucky, I'm lining up a few jobs  |

This has been an interesting day. As I have to have some patience, the Quads are going to have to wait until near the end of September before they get looked at, I've been having a little bake off to see which of my various pairs of speakers is going to do its duty until the Quads retake their rightful place. There are four contenders: JBL TLX16 Teufel Ultima 800 Home builds with 12" chinese bass unit / HF1300 / T27 Kef 101's and REL Quake. JBLs immediately fell at the first hurdle - raw, no real bass control and rather boring. The Teufels have fantastic bass, deep, clean and musical. But.... there is a problem at the top end. They have set the crossover points at 350 / 2000. I find there is some sort of spike there that upsets the midrange for me. They are very 'impressive' but having got used to the Quads, they are just not quite there. It will be interesting to see how they cope in the big lounge when it's done. I may well rebuild them at some stage but with a more conventional mid and treble. Home builds immediately sorted the top end and sounded really good at first. Gradually though, I became aware that there is a problem at the lower mid. Its too thin and lacks sufficient body - probably a result of using the 12" as mid as well. They always were just an experiment. Almost very good but no medal. So, its down to the little Kefs. Not much to say. I sat down and just got lost in the music. Tonally spot on and the REL just fills in enough to sort out the bottom end. They are just so damn small I remember hearing them side by side with my tutor's LS3 5As and preferring them, they seemed more alive. How am I going to impress all my mates with women's speakers? PS. I suppose the real surprise is how a pair of KEFs that are donkey's years old and cost me £20 at a boot fair sound so much more natural that a pair of the latest all singing, all dancing €3000 pair of German speakers. |

Sounds like something my mrs would say. Just because there's a space doesn't mean it needs something in it! Or maybe do a bit hairdressing while you're using girlie speakers.... |

It's good that you have some alternative choices Gordon and great that you've found one that works for you. I can't recall ever hearing a system with those little KEFs, I'd be surprised if I didn't though!

If you open them up Gordon remember there are some high voltages in there, although the caps should probably have discharged after a few hours. Hope they get fixed soon - a pair of baby Kefs are not the same at all, although always good to have reserves when the main unit goes down.
Reminds me I need to tackle mine when I am back. And then shift, at the very least, the Lowthers. Looks like the listening room chez Sutton is not going to be changing in 2014 or 2015. Frustrating house hunting fiasco this year, although as ever we have learned a lot.
Time for chillin - sunbathing here - bit of proper music when we get back.
Hope you are back up with the Quads soon

Hope you are back up with the Quads soon Ta, its gonna have to be down to Alan. I have absolutely no idea what I'm doing. Anything with mains voltage is a no go area for me. The KEFs are surprisingly good actually, its possible to forget they are there and just get into the music. Thats what its about after all. |

More developments!! I sat down again for serious listen tonight and as I couldn't believe the Teufels would come off so badly against the KEFs tried them again. The sound was a bit one sided!! Then it cleared, then it shifted suddenly to the right! WTF is I believe the expression. Ear up close revealed that the wonderful looking metal mid range driver was very quiet indeed. Fortunately, the mid range drivers in the JBLs are the same diameter and 8 ohms so a quick swap and suddenly they sound terrific!! OK the driver might not be as designed but it seems pretty much the same level or maybe a fraction fuller in the midrange but as they sounded so thin before this is probably a good thing. I assume its been on the way for a while. Orf to beddy byes as Ronnie is tired and the speakers are underneath the bedroom. Much more listening tomorrow. Oh wot fun this is  |

Oh wot fun this is Do you think you might have a fault in your amplifier/system ? Two speaker failures in one week ?? I don't think so Dave. The Quads were on the Stereo20 and the right hand one went completely. The Teufels were on the Musical Fidelity A100 and the left hand mid range unit went. Just one of those coincidences I think. In some ways, I'm quite pleased about the Teufels. The mid range is one of these high tech Titanium units and, dare I say it, have always sounded a bit too bright and 'metallic' to me. Having installed the paper coned units from the JBLs, its all much more natural and 'warmer' sounding. The JBL units are operating in a much narrower band than they usually cover (350 - 2000htz) and sound better for it to me. I do wonder how much truth there is in the old one about the Japanese and Germans having different tastes in sound. I'm sure I remember some Japanese manufacturers voiced their speakers differently for the UK market as they were accused of being a bit sharp. The Teufels measure very well - at least they did with the original units in - but have never sounded just right to me. Now they do. Still lacking the magic of the Quads but they will do for now. The little KEFs can go back to their usual bedroom duties and I can show of my men's speakers to my mates again |
