I have a number (approx 20) of Practical Wireless Magazine from the 1950s, a bundle of Glass Audio Magazines (around 50) and some early HiFi World supplements...
Hi everyone. I just joined yesterday and I wanted to introduce myself, and present my current situation for anyone interested in advising. This may get a...
... Hi Devon - welcome to the group. I hope I can give some useful advice. Firstly, I would say that the only reason for using silver interconnetion wire is...
Add to point 3 - 'Check for ground continuity between the chassis and the mains earth connection at the mains plug. Check the mains fuse, and if it is intact...
Hi, I'm thinking of getting one of these: http://www.goldpt.com/sa4.html . Can anyone tell me which attenuation level I should go for 25K or 50K? I have a Quad...
Ben When it comes to passives I'm not entirely sure it makes much difference, I've played with 10k, 50k and 100k and they did what was expected. If you are...
I have just purchased a pair of these amps. Can any members help as I feel the sound reproduction could be better. The sound is rather harsh and could be...
Hi, First thing to check that the output plugs are wired correctly for the impedance of your speakers. The QUAD 50E has an output transformer - you match the...
This is an obvious case of dried out / worn electrolyt capacitors. Also check the quiescent current and the voltages. Stefaan www.dadaelectronics.eu...
Hi Paul You can download the owners manual here: http://www.hifiengine.com/manuals_type.php?man=Quad&mod=520 Description "The Quad 520 is a two channel 100 to...
Did anyone tried the power switch wafer on a Goldpoint attenuator in a Quad 33 pre? See: http://www.goldpt.com/prices.html Not cheap, though seems like a nice...
Hi All I've been idly thinking about this for some time, Just wondered if any of you had any comments. Once upon a time speaker impedance was commonly 15 ohms...
... Hi Graham, as you know, the impedance figure of a speaker is a nominal value intended as a rough guide to a quantity which varies greatly with frequency -...
I wonder whether that's why so many newer speaker designs sound (to my ears anyway) 'laboured' or 'sluggish' or 'slow', and don't 'breathe' the way the older...
Uncanny coincidence! In an e-mail last Sunday I included the following with regard to the qualities of certain vintage loudspeakers........ "Classical music...
Missed your post, but surely 'precision engineering' is cheaper in real terms than it was years ago, what with CNC stuff et al? Chris [Non-text portions of...
Hi again. About a week ago I sent an email introducing myself and presenting my repair/upgrade case. I accidentally mistyped one of my problems: I have an...
I should have been clearer that the post was a private e-mail, Chris. One might well think "Precision Engineering" should be cheaper in real terms but...
I think there are logical answers to these questions, actually. First of all, a speaker is not sluggish as such because of low sensitivity. It just uses more...
I purchased this cable from Flashback in the UK for a Quad 303 that did not work out. It is a 2-meter length of their 'Performance' interconnects featuring 2...
I wouldn't disagree with anything that has been said, but one of the reasons I like 'lively' speakers is because they make music a fun experience. Even Wagner...
Hi, I'm experiencing a random problem with my late model Quad 44 (with RCA sockets). Sometimes I seem to lose the right hand channel. If I put my ear to the...
Hi Trying to track down intermitant problems can be a pain. It would probably be best to try and isolate each item. One big clue though is that you say it goes...
I shouldn't disagree either (particularly with two respected professional reviewers) so I'll gather to myself the most logical of what you have both said. ... ...
Well stated, Chris. I love my Quads...as much as my Lowthers and Klipsch La Scalas. Now you've provided an insight into why. However, maybe one day I'll try...
Professional reviewer(s).....hmmm. I have always regarded my reviewing as a 'pro bono' activity ever since my father instilled two things into me; the first...
... Hi Chris - This thread has ramified into an interesting area ! I do not want to be argumentative, but my instinct as an engineer and a physicist rang some...
