Hi I have a Quad FM 3 Tuner and the Mute Threshold button is missing. I have looked in the circuit diagram and by looking at the tuner have deduced that this...
Hi all, I know a little about repairing 63s but I've been asked about a 57 problem . I've never pulled a 57 apart or know how easy/difficult it might be. ...
Chris M. ... snip ... The dust covers need retensioning by applying heat from a heat gun. -- Best regards, Goran Finnberg The Mastering Room AB Goteborg Sweden...
With great emphasis on carefully, with respect to use of a hair dryer. Too much heat in one spot and the dust cover will hole and the only remedy is to remove...
Absolutely agreed and would add that a hair dryer is much safer than a DIY or industrial heat gun. Much less likely to do damage with it as heat is less...
... As I have done Quad service on a paid professional level in the misty past I have some considerable experience doing this kind of work on several hundred ...
I too have used expensive professional heat guns (in the defence electronics industry and for many years). With the various adjustments on them and in...
Thanks all. The loose dust cover seems to be the culprit by consensus. It would certainly cause what they describe as the rattle. I'm surprised though because...
Chris, The bass panel dustcovers are (should) not Mylar but a very easy shrinkable film. Don't start with a heat gun on them but use a hair dryer. For the...
Dear all, I have wondered for quite a while (in fact several decades) whether the dust covers are really necessary. Some time after the introduction of the ESL...
Hello Frederik, Running the ESLs without dustcovers will make them develop problems within months I suppose. Ones you have seen panels used with teared or none...
Hello Group: Well, after 35 Years my Audio Hobby is coming to an end. I reached a point in Fidelity that was higher than I ever hoped to achieve, so I will...
PANIC, HELP....PLEASE!! I've just turned on my 63's to find that one speaker has a feeble output!! I've swopped them over so it's definetly the speaker not...
I am interested to see that you have a 914, I have 2 one which has been a shed for the past 25 years and one which I hope to get MOTd in the next few days. I...
I had a similar experience a couple of years back. Failed capacitor - replaced (for a small fortune) at Quads in Huntingdon whilst I had a day out at the RAF...
It does seem to be electrical rather then mechanical that's causing the loss. That's good IMO. Yes, check fuse and then hand the speaker over to somebody who...
BTW folks. Regarding repairing 63s. To measure the 6kV I have used a 40kV 1000:1 probe into a DMM of 20Mohm/V impedance. I found that this still under read the...
Dust cover I suppose in a pristine air conditioned environment removing the dust cover might be alright. However, we live in a practical world. The world is...
Hi there Haven't posted much,but would appreciate any group members input on Harbeth speakers with Quad amplification. I am a happy Quad user of over 30 odd...
I have been using an all Quad setup for the past 30 odd years; 66/606 II/ 67CD/66FM for the last 16 years. I am exploring the idea of using more sophisticated...
... Hi Paul, I am using QC-24, 909 & CDP-2 with the Harbeth S-HL5 It works great and sounds great! I love this combo. Do have a listen to the M30 and S-HL5....
Felix, Are you sure you are comparing the M30 and SHL5? I can't comment on Harbeth's current pricing but I can definitely state that these monitors are NOT the...
I have a Benchmark DAC1 and have used it hooked up directly to a Quad 909 (CD was my only source so I did not need the DAC1 pre). I can only describe the sound...
The notes below, from the Tesla chat group some years back, might help anyone wondering about measuring the sorts of voltages used to charge the panels in Quad...
Very interesting. Yes, ES metering is a better way but pretty impractical for most of us. By calculation the 63 has a 400Mohm output impedance of the 6kV...
