The 1812 Overture and Tonearms
Several years ago I had purchased a Telarc album of The 1812 Overture
and a M&K Direct to Disc album titled the Power and The Glory. The M&K album is pipe organ music. Both albums provide challenges for some turntables to play. At the time that I had purchased these albums I had (and still have) a Dual 1237 turntable (cost $137.00) with a Shure M91ED cartridge. The turntable played these albums without any apparent trouble. One day, a long time ago, I took the 1812 overture to an Audio Store and I told the salesman that I wanted to hear my album on his best system. The salesman showed me a Micro Seiki turntable,a McIntosh amplifier, and a pair of Ohm F speakers. The sales man put my album on the turntable and preceded to tell me the virtues of this system I was listening to,then all hell broke loose. The Telarc 1812 has cannon shots in it and some of these are claimed to be as low as 6hz.The tone arm went skating across the album.The Big McIntosh amplifier shut down,and I was told never to bring That record in his store again (funny I bought it there) and I was shown the door.On the way out the door I told the salesman that my cheap Dual played the album just fine. Several years have past and I had acquired a Technics SL-1400MKII and I got out the 1812 overture to check out some new subwoofers,the cartridge was a Shure V15 typeVMR. History repeats itself and the tonearm go's skating across the album.I increased the tracking force to 2 grams and the tonearm could not track the cannon shots. Next I put on the M&K album, and when the tonearm came to the low bass passages the the needle jumped out of the groove.The Technics turntable was of the same vintage as the Dual turntable but cost much more ($440.00). I got out my old Dual 1237 and put the Shure V15 on it and listened to both albums without any obvious stress to the turntable. Now for the whole point of this discussion,I am looking for a tonearm to put on an AR turntable. The current fashion in tonearms seems to be medium mass tonearms such as the Rega's and SME's.Will medium mass arms and the Shure cartridge track my most challenging records? Should I be looking for low mass tonearms? I would hate to invest in a tonearm and it not play the records that I have. Is the Dual tonearm better than it's price would suggest? Would a vintage Infinity, Grace, or Formula IV tonearm be a good choice? |

A common saga about that LP. -- Yes, some (often cheap) turntables can play through that section without being thrown off, but nothing could "play" that record as cut. The report I heard was that, due to a cutting flaw in the first release, a turntable would have to reverse direction for an instant in order to follow the record surface exactly. I question the wisdom of that store for throwing you out. Everyone in the trade learned about that record, and those who knew what they were doing could come across as true experts by explaining why that record was essentially un-playable. (by the way, if you play the thing often enough, that surface flaw may break off and give your turntable some relief) If I was faced with that certain kind of customer who came in with the obvious intent of surprising and/or embarrassing me while trying to play that cut (somehow thinking I was too inexperienced or dumb to know what was about to happen), I'd pick an amplifier with an easy to blow and replace fuse, then let him have his way (no, I'm not sexist -- but it was always men who did that). When the fuse blew, the customer was either embarrassed or elated, but always left quickly and ended the pointless exchange. I don't think it is a good idea to use the criteria of being able to play that LP as the foundation of your arm-cartridge choices. ----------------------------------------------------------- SPAM: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, SPAMers are ruining my mailbox] ----------------------------------------------------------- |

The salesman showed me a Micro Seiki turntable,a McIntosh amplifier, and a pair of Ohm F speakers. I had a pair, actually 3 Ohm F's once. In fact they aren't the greatest with low bass. Not a lot of Xmax. The sales man put my album on the turntable and preceded to tell me the virtues of this system I was listening to,then all hell broke loose. The Telarc 1812 has cannon shots in it and some of these are claimed to be as low as 6hz.The tone arm went skating across the album.The Big McIntosh amplifier shut down,and I was told never to bring That record in his store again (funny I bought it there) and I was shown the door. I'd suspect a good dollop of acoustic feedback as well as everything else. On the way out the door I told the salesman that my cheap Dual played the album just fine. Your Dual might have been mounted more securely, with more isolation due to architecture and furniture. Several years have past and I had acquired a Technics SL-1400MKII and I got out the 1812 overture to check out some new subwoofers,the cartridge was a Shure V15 typeVMR. History repeats itself and the tonearm go's skating across the album. In contrast my house is on a concrete slab. I had Ohm F's and I had Ohm F's with a subwoofer. No problems. Turntable was a Thorens TD125 and SME 3009II tone arm. V15-III & IV. I increased the tracking force to 2 grams and the tonearm could not track the cannon shots. Next I put on the M&K album, and when the tonearm came to the low bass passages the needle jumped out of the groove.The Technics turntable was of the same vintage as the Dual turntable but cost much more ($440.00). It's not vintage, and its not cost, its engineering. Note that besides a concrete floor, and being in a robust cabinet in the next room, the TD-125 has some pretty heavy duty shock mounting of its own. The arm and TT are mounted on a flexibly mounted subframe. I got out my old Dual 1237 and put the Shure V15 on it and listened to both albums without any obvious stress to the turntable. It's possible that the tone arm had a higher resonance, and to some degree acted as a low pass filter. Also, the Duals did have some kind of built-in shock mounting. Now for the whole point of this discussion,I am looking for a tonearm to put on an AR turntable. The current fashion in tonearms seems to be medium mass tonearms such as the Rega's and SME's.Will medium mass arms and the Shure cartridge track my most challenging records? IME probably, almost certainly if you avoid the other problems I've mentioned. Should I be looking for low mass tonearms? I would hate to invest in a tonearm and it not play the records that I have. Is the Dual tonearm better than it's price would suggest? Would a vintage Infinity, Grace, or Formula IV tonearm be a good choice? Probably, the ultimate in cheap, effective anti-feedback mounting for a turntable is a patio stone sitting on top of a somewhat-inflated bicycle tube. Works for holograms and lasers, works for audio. |

Sorry, this doesn't make sense. How does a cutting lathe produce a retrograde cut without itself reversing direction during the cut? As I recall that LP, it was simply a case of an enormous recorded velocity that was pretty well impossible to track with *any* cartridge, even the super-compliant ones like the V15. I saw a photomicrograph claiming to be of the cannon shot and there was a clear "hook" in the groove wall. I know the cutter couldn't back-up and didn't intend to cut a hook. Perhaps the impulse of the cannon shot excited a resonance in the cutter or there was a weakness in the wall at that spot and damage occurred at a later processing step that resulted in the hook. (perhaps is was an enormous horn that was not fully removed or the metal was bent during the horn removal attempt?) ----------------------------------------------------------- SPAM: wordgame:123(abc):14 9 20 5 2 9 18 4 at 22 15 9 3 5 14 5 20 dot 3 15 13 (Barry Mann) [sorry about the puzzle, SPAMers are ruining my mailbox] ----------------------------------------------------------- |

I did track it successfully but only with the SMEIII/Ortofon SME30H. Kal |
