How do these heads look ?
Hi,
Aside from some tape oxide, the rather dark photo and limitations such inspections impose, I see NO visible flat spots anywhere on the tape lifters nor heads ... These appear very low use. Again, just by what you see with your naked eye, do you agree ? Here's a direct link: http://members.shaw.ca/ftp_pro/heads.jpg Many thanks for your time. Daniel |

Daniel -- Overall, the machine seems to be either little used or very well cleaned. Yes, there aren't visible worn parts. The heads look fine to me. I hope the uppermost track shows as if was somewhat dirtier but not worn. Cleaned heads would tell me naturally more but again, the heads and the machine looks fine to me. If you load this photo in an image editor, and then invert colors (negative image), you'd see the contact area more clearly. Edi Zubovic, Crikvenica, Croatia |

I looked at the heads and tape path in person yesterday (and in better, more consistent light) and it all looks very good. The heads indeed were a bit dirty from oxide and the seller did clean it up before I saw the machine. The tape path indeed looks near new and shiny and there are no flat spots on the tape lifters to speak of. Thanks for your helpful reply. |

Again, just by what you see with your naked eye, do you agree ? another incomplete question brought to you by rec.audio.pro That link seemed to have problems today, but let me ask - are you planning to use the heads or the tape deck? I guess I know the answer to that, but is the deck worth worrying about? What's the machine, and what are you thinking about using it for? Heads are important, but it's really only said about fairly pricey (originally) tape decks that they're worth what the heads are worth. Low grade consumer tape decks are rarely good performers by today's standards, even with brand new heads. |

Mike Rivers (that's me) wrote: That link seemed to have problems today Ah, there it goes. Looks like a TASCAM *8 1/2" 8 track. Hard to tell about the play head. It looks like there might be a groove worn down at the bottom, or that could just be the lighting. But the tape deck is probalby worth saving and using (answering my previous question to you). The real way to tell is to clean the heads and tape path thoroughly, demagnetize them, then play a calibration (alignment) tape on it. Look for ragged amplitude at high frequenciesl. Since this machine has sync playback, you can check the record head as well as the play head just by switching the monitor between Sync and Repro. (the REAL real way is to remove the heads and send them to JRF Magnetic Sciences for evaluation) You should have a calibration tape and some test equipment to keep the recorder maintained and aligned. If you don't have one and aren't ready to make that investment (it's probably close to $200) then don't worry about the heads. You won't be able to keep up with the maintenance. |

Again, just by what you see with your naked eye, do you agree ? You can't see anything with the naked eye. The heads could have been relapped several times and be about to fail. The gaps could be opening up and you wouldn't see anything without extreme magnification. The only real measure is to check the head inductance. This gives you a very accurate measure of the wear. One thing you can do, though, is just try and align the machine and see if the EQ settings on the edge tracks are near the settings on the center tracks. --scott -- "C'est un Nagra.

Doesn't look low wear to me. Isn't that the normal "groove" resulting from the lapping process during the original manufacture of the head? From the limited view in that photo, it looks pretty much unused. (Based also on the cleanliness of the tape path, particularly the flutter roller which is likely textured and more likely to pick up o xide dust during use.) |

Heads are important, but it's really only said about fairly pricey (originally) tape decks that they're worth what the heads are worth. Low grade consumer tape decks are rarely good performers by today's standards, even with brand new heads. It's certainly not a consumer deck. It's a 58 tascam. Yes, I know I'm buying the heads 'cause if they're shot I'll be getting a nice heavy paper weight. The heads would cost more than the machine to get replaced. Although from inspecting the tape path this seems a low use machine. |

The seller would give me several days and in which case if it doesn't pan out, I'll return the recorder to him. Thank god it's local and not an ebay thing where I'd have to contend with shipping ... |

Additionally, the seller did mention that the machine was a one owner
unit and that he used it in his own private home studio but as getting tape and cost of it was a bit of a hassle, the recorder was used very little. |

Have you ever owned an analog multitrack? Or lived with one that is old, even if it didn't have a lot of miles on it? I've had students, against my recommendations, buy them and end up spending a lot more $ on them than they ever anticipated. If you really wanna add analog tape to your arsenal, let me suggest you get a stereo half track to dump your mixes too. My 2 cents for free ; David Correia www.Celebrationsound.com |

I've bought and sold multiple mtr-90's over the years and a head report was always part of the transaction. But the head report for this deck would probably cost as much as the deck ... Something like the Otari MTR90 and your typical PRO designated recorders are lots more expensive, have a lot more miles than many semi pro or narrow track format machine like the TASCAM, TEAC etc .... The pro machines are usually found in pro studios with people who actually know a thing or two about these beasts and I'm not at all surprised that a head report is usually a part of the transaction. My point is that anything less than a pro machine, most of the time, does not involve a head report for various reasons and one of them, like you said, it's the expense. Have you ever owned an analog multitrack? Or lived with one that is old, even if it didn't have a lot of miles on it? Yes, I have several older TEAC and TASCAM machines with perhaps 50 - 100 hrs from the previous owner. Parts are cheap and plentiful and it's easy to maintain and I don't complain about the sound. I'm lucky I guess with spotting low use machines with plenty of head life left. I've had students, against my recommendations, buy them and end up spending a lot more $ on them than they ever anticipated. I know some who have done the same, bought a machine cheap and then spent weeks trying to get them to work properly. They made it worse and spent more than the machine is worth on parts etc .... It's quite a task being careful what you buy (and knowing a thing about it too) but then, when the machine is in good condition, it's always good to bring it to a tech to bring it up to spec. If you really wanna add analog tape to your arsenal, let me suggest you get a stereo half track to dump your mixes too. I've got a half track as well and use it for tape echo, dumping mixes etc ...... I'd rather record to an old TEAC then have a hand at digital. I've gone through all that and would never go back. .... I'm not an old guy who grew up when tape was king. I've grown up when LP's and tapes were being replaced by CD's and digital so it's not that I've grown up with analog. I went from years of experimenting with digital to analog and I don't look back. I have nothing against people going digital or working with it but it's not for me. I've spent the last 5 years carefully searching out local deals. I've passed on more deals than what I accepted. I just don't buy any old thing, no matter if it's a semi pro or pro machine. |

There's always the possibility of a low use one I suppose. I'll stick to the 58 for now but thanks anyway. |

If the 58 is in good shape, the price is reasonable, and you can see getting a year or two's use out of it, go for it. |

In the case of a cheap narrowtrack machine, it's not worth it. But for studio machines, most of the sellers will invest in a head report from JRF or Sprague and have it available to potential buyers. If they refuse to do that, it's a sign that something is wrong. Narrowtrack machines, though, are disposable. If the machine can be aligned, buy it. When the heads go, throw it away. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
