Quad ESLs - 57 or 63? Pinkerton's lies debunked

"Andre Jute" ... The Quad Electrostatic was on sale in 1957 - and I have numerous original Quad brochures from that time which clearly show that it was on sale in 1957. It also appears in the HiFi Year Book of 1958 , this being the earliest one I have. I don't know where your 1966 date came from but it isn't correct. Pinkerton is an idiot who owes me and Phil Allison an apology. I'm not holding my breath. I'm sure Phil knows better too than to expect either truth or good manners from Pinkerton. * One of the ESL57s I owned until recently was s/n 00246. Do you expect it was made in 1957 ??? ............. Phil |

Oh, I forgot, you're so far gone that you don't know the difference between lies and reality. I'm not inclinded to be so tolerant, Mike. No ****! Pinko got this dumb misunderstanding from the Quad site where they say that from 1957 to 1966 PJW developed electrostats. That's all it says; it can mean anything or nothing but in fact is specifically intended to mean nothing without being challenged. Pinko was just tripped up by a copywriter who probably the day before wrote about soap and the day after about salad cream. It wasn't some old Yarpie hack who normally writes potboiler 'thrillers', was it? The blustering fool Pinkerton doesn't just tell a lie, he uses the lie to malign an audio designer, Peter Walker, whose feet he isn't fit to lick: Just another typical lie from the sad Jute sack. And it's revealing that Walker had already started work on the '63 three years before the '57 even went on sale in 1966. In other words, the useless poseur Pinkerton claims Walker sold the 57 while knowing it wasn't good enough. The '63 is an *entirely* different speaker, and if the tired old hack Jute knew anything about industry, he'd be well aware that you use sales from existing products to develop better ones. The '57 was the best that PJW could make in 1957, but he knew that more was possible, and he took a *long* time to get the '63 ready for production, during which time the '57 kept the cash flowing. This is the speaker that was voted the greatest audiophile invention of the 20th century! But Pinkerton---a failed salaryman, an "engineer" who for a living essentially cleans up the computers of more creative people!---thinks its creator was a fool and a crook. What a pluperfect ****** this Pinkerton is. What a pathetic liar Jute is - but evertone on RAT already knows this. Pinko starts hurling insults every time we catch him out in these silly mistakes and lies. He calls Phil Allison "a cretin" for correcting his (Pinkerton's) ignorance. Allison *is* a foul-mouthed cretin - as are you. On this occasion, I was wrong. Some of us accept being wrong, add the truth to our memory banks, and move on. You however, are a sad and bitter old hack, crying into his Guinness about the god old days when you could have black kids shot at dawn. Pinkerton gets it grotesquely wrong and then screeches at me "you're too used to writing pot-boiler fiction". You are, that's obvious with every one of your pathetic self-pitying posts. I can't be bothered to straighten out this poor moron Pinkerton who cannot even distinguish engineering texts and other professional handbooks from literary fiction. There doesn't seem to be anything of value in Pinkerton's life, just spiteful lies about more creative men. He's worthless. As worthless as 'Andrew McCoy'? I think not....................... -- Stewart Pinkerton | Music is Art - Audio is Engineering |

A short synopsis, for those who don't know this clown: Born 1945 in Oudtshoorn, South Africa, Andre Jute McCoy was educated at the Universities of Stellenbosch (South Africa) and Adelaide. He has had a variety of occupations and interests, including advertising (he became a partner in an advertising company at the age of 23 and retired at 26), intelligence officer, racing driver, big game hunter, actor, critic of theatre, music and art, magazine editor, public relations officer and professional gambler..... Also wrote some potboilers under the name Andrew McCoy, between 1978 and 1988. This sad old clown leaves Walter Mitty in the dust, and you can judge his basic character from his self-admitted time as an 'intelligence officer' - ever read about the lovely boys of BOSS? -- Stewart Pinkerton | Music is Art - Audio is Engineering |

"Andre Jute" Phil Allison ** One of the ESL57s I owned until recently was s/n 00246. Do you expect it was made in 1957 ??? I don't know, Phil. ** Ah - such simple honesty is genuine rarity !! But I don't see how such a low serial number could be of later manufacture. ** That is my assessment too - but I am not sure what month in 1957 the esl57 " train " got a head of full steam going. It seems to me very unlikely that fewer than 246 speakers were sold in the first year; many multiples of 246 sounds more like it. After all this wasn't some marginal technology sneaking in by the back door from an unknown company, this was a long-awaited, much-discussed, earthshaking new technology from Acoustical, already back then a widely-known leading manufacturer with a Rolls-Royce reputation, which furthermore had the stamp of approval of the world's most competent broadcast house, the BBC, all over it. Which leads me to another point: it seems very likely that orders from the BBC in the first year far exceeded 246. ** The "Quad Electrostatic Loudspeaker " s/n 00246 I owned was privately imported into Australia by someone I never actually met - but obviously, he was a "man of wealth and taste " ( apologies to Jagger and Richards). I picked it up for AU$80 in 1974 - " I call that a bargain, the best I ever had " ( apologies to P Townshend ) Simply for interest: On a really good product there is a smaller but very noticeable peak again when it is replaced as people stock up or take the plunge before it is too late (1). In the case of the ESL57 this particular peak must have been strong enough to persuade PJW, an outstanding businessman, to keep the ESL57 going after the launch of the ESL63. ** Not to mention that the ESL57 was a good deal cheaper than the '63 and the component parts were still in strong demand for spares - Acoustical did sell over 60,000 of **them** after all !! ............ regards, Phil |

Here's a little clue. If your speaker still has the original epoxy EHT block, remove it (will require a bit of soldering job) and look at the back (the surface that cannot be seen when properly assembled). There is a small metal tag stating the month and year of manufacture of the EHT block, but still the best approximation to overall speaker manufacturing date. I have seen this happen in all 6 samples I have refurbished. Oddly, the date shown and serial number do not correlate exactly to the list that circulates around about Serial # and Yr Manufacturing.

Instead of a neat block, there was a bundle of (selenium ?) stick rectifiers looking very much like a bundle of red fire crackers - each about 3 inches long and 1/2 inch diameter. I contacted the Sydney agent for Quad (a firm called " British Merchandising " in those days) and spoke to a gentleman who sounded exactly like a graduate from Eton College. He was able to supply me a new EHT block and also advised that I carry out a modification to the passive network under the audio input transformer for which he could supply a diagram. When I delicately enquired if this modification involved any expensive omponents - he replied : " Nooooooh - not at aaalllll - should only cost you a few *pence* !! " ...................... Phil |

The size was and is still a problem for most. Considering that a box design can produce the same sort of level and response from something a fraction of the size. In practice they take up just too much space for the average UK living room. So only likely to be bought by dedicated enthusiasts with a meek spouse. -- *Not all men are annoying. Some are dead.

Networks, in my reprint of 1970, possibly restored, though without comparing your edition and mine I cannot quite see how. The chapter does not constitute an entire signature missing, that's for sure. (A "signature" is a large sheet of paper printed both side, folded a certain way, sewn into a book with other signatures, then guillotined on three edges, after which the pages appear maginally to be printed right way up, page and verso. A signature is theoretically any multiple of 4pp-- thnk about it--but in practice in book printing by 1968 already very rarely less than 32pp.) Ross Matheson Smart idea, posting the photograph. It seems to me "fair dealing". Don't post the entire chapter, however short; that would definitely be viewed in some quarter as an infringement precisely because it is the whole of a self-contained unit. Andre Jute |

So Peter Walker elected to scale down his new design and release a the Quad ESL in a more practical size. I have often heard and read the same story. I wonder if it makes sense though. Why should Walker, a brilliant businessman, have come to believe that squat wide speaker would be mroe acceptable than a tall, fiarly narrow one. It is true that average topclass speaker at the time was a squat corener horn, with doors folding open as wings to the side in many cases, but it was not short, it was the height of a table or taller. In addition, Walker himself had already made a tower-type of speaker such as is now common, though he called it a pipe. (Ross will give us the reference, also in the Briggs book he has.) So why should he believe a very wide speaker would be more acceptable than a very tall one? Dinna make sense. I think there were technical reasons, possibly to do with the very substantial high frequency improvement betwen the proto and the finished article. it is interesting that the proto seems to be in fact two ESL57,on top of each other but with narrower panels. The question that jumps instantly into my mind is, Did he find that full-height panels on the proto gave rise to uncontrolled resonances? We will probably never know, but we are so far off the original poster's question here that we may as well indulge ourselves in a little speculation. Phil Allison wrote: Poms are renowned for preferring neat, natty and compact items - unlike the Yanks where the original larger version would have very likely been far preferred as the Quad 989 is now. ............ Phil I think the tall proto is "neat, natty and compact", Phil, much more attractive (and still modern) than the ESL57 which stylistically was a throwback to the 1920s. In the fifties, Britain had no style; it was utterly frumpish. The appearance of the 57 was acceptable because it rose above the wretched style of the period by being so thoroughly 20s, but then it wasn't difficult to rise above the swamp of dejection that was Britain in the 50s. (That is why Mary Quant and Carnaby Street and the Beatles burst out like a boil exuberance at the beginning of the 1960s.) Andre Jute |

"Dave Plowman (News)" How do you get 'resonances' in a speaker without, effectively, a box? ** Boxes will have internal sound pressure reflections between the sides - this is one source of resonances. The materials the box is made from resonate as well - just tap one of the panels with your knuckle to hear them. The materials the drivers cones and domes are made from ( paper, plastic and metal) have audible resonances. All these resonances operate simultaneously with a conventional box speaker system, they "colour" the sound heard and are impossible to completely eliminate. However, a sheet of plastic film with barely any mass ( so no ability to store energy) which is driven by a coherent (electrostatic) force that is spread evenly all over its surface is virtually resonance free. A simple demo, used by Peter Walker, is to hold a frame with a sheet of such plastic film in front of someone's face when they speak and note that the sound is quite unaffected. .............. Phil |

Cone speakers have notoriously bad resonances in their cones, and ESL have resonances in their panel diaphragms. Boxed speakers have the box to worry about as well as the cone.
