Description
... In 1971, the AEG-Telefunken M15 was introduced, with what I consider to be the best tape transport the company was to design, and one of the finest tape transports ever made, if not the best. It is very minimalistic, having nothing more than the bare minimum of parts, yet packing all the features it needs to guide the tape confidently, with wow and flutter remaining inaudible even to the most discerning listeners, who claim to always be able to hear it on tape. Several years ago, a classically-trained musician asked me to demonstrate the audibility of wow and flutter on one of my Telefunken machines, by recording and playing back a 1 kHz tone from my bench oscillator. He said that he could hear it every time on all the tape machines he had ever used. The idea was to compare the sound of the oscillator directly played by the speakers, to the oscillator recorded to tape and subsequently reproduced on the same set of speakers, switching between one and the other. He claimed that the speed instability of tape transports was always audible to his ears using this test. So we tried it, using an unlabeled switch. After a few flicks of the switch, he looked at me confused and asked, “is this the tape or the oscillator?” I thought it was the tape, but I was not entirely sure. I certainly couldn’t tell by the sound, and neither could he. He then asked, “are you sure one of the two is really the tape?” and I said yes. So, a couple of flicks later, he just suddenly pressed the Stop button on the tape machine, and the tone stopped. It was the tape, and neither of us could tell. I then explained to him that I didn’t think the test was sensitive enough, and that it would be best to use a 3,150 Hz tone instead, or even 10 kHz, which we did, but we were still both unable to tell which one was which by the sound alone, and we also could not hear any wow and flutter with music. === Warranty 1 month.
