Does a cat vomiting a generous amount of unwanted matter through the grills of an very expensive Panasonic state of the art TV (for the era) count?
On the audio side of things, I have a tale which I am still exceptionally sour about 6 years down the track. I will not mention names or dealers but when the Goldring 2000 series came out, I forked out for the top-of-the-line 2500 model. I removed the stylus itself during the tonearm install (for what I felt was a simple safety precaution) and went to replace it after installing the body. At this point I should have stopped and called the dealer right away, even though the styluses on these cartridges are clearly intended to be user-replaceable as they are supposed to be a simple pull out - push back in arrangement.
But there was some sort of dark, dampening absorbent type material that tightly surrounds the receptacle where the stylus mates with the interior of the cartridge. It was sort of like a very high density spongy, rubberised compound. Now I don't know if was due to a temperature change and / or humidity change, but despite my best efforts, the stylus would not go back into the cartridge body some 30 minutes after being removed. It had been a tight fit to begin with and I did notice that as soon as the stylus was removed, that spongy, rubbery stuff seemed to actually visibly expand, making the existing receptacle smaller than it previously was. I was a bit perturbed but thought to myself, well, Goldring must know what they are doing as these styli are replaceable - supposedly by anyone...
But I pushed lightly...double and triple checked I was properly aligning the thing but it wouldn't go in. I thought to myself should I try more pressure or ring the dealer. I tried more pressure, thinking to myself that Goldring must have just engineered the thing for a very tight fit and that it would push back in with sufficient pressure. But since this is a fail story, you can imagine what happened next. Damaged stylus and damaged receptacle in the cartridge body.
I immediately contacted the dealer. I explained thoroughly and concisely step by step what had happened. I explained that even with the utmost care and patience, the stylus would not return to the cartridge body and that I regarded this as a manufacturing issue since there was no possible way I could see anyone returning that particular stylus to that particular cartridge body without damaging it. I was also at pains to explain that upon removing the stylus, I noticed the dense rubbery surround actually expanding over the opening and was wondering why that should happen given how tight the fit was to begin with.
To cut this story short, I got nowhere with the dealer even after protracted emails, phone calls and complaints. To this day, I don't believe I did anything unreasonable and that the cartridge - well at least my particular one - was to blame - specifically that the surround is some rubberised compound that has very high levels of friction to begin with and secondly that it noticeably expanded over what was already a very tight opening as soon as it got any breathing space (by way of the stylus being removed in the first place). And from an engineering point of view, the rear of the stylus was not a tapered fit as you might expect if you have to push it through a very narrow, high friction opening, but was open and square ended - the worst possible thing. This is the reason why injection needles are not designed with a square end and sharp edges at the end where it goes into your skin!
This was the one and only mishap I have ever had and obviously that means I have handed cartridges countless times and never had the slightest issue. I don't think the dealer did the right thing by me, nor did the importer when the exact circumstances were taken into account. To me it is almost the same as a car that has an external rear view mirror that decides to get twice as big when you are moving into the tight garage or parking spot!
I am still mightily peeved years after this happened. That was $500 US down the drain and to add insult to injury, when the cartridge was returned to me, they had damaged it even more than I had. The only thing that makes me feel any better about this is that I gave the director the company a heck of a serve and do not regret any of the choice words and expressions I mouthed his way after all the patience with him and over-and-over again explanations over emails and phone calls officially lead to nothing (I was polite all the way until he said they would not do anything about it). Furthermore, when I told him he lost my business forever, it does make me feel better considering the many thousands I have spend since on equipment and records from dealers other than that one since then.
