Vintage DD turntables. Are we living dangerously?
Fleib, Congrats on your TT-81. Any ideas on how you're going to mount it? Can only speculate on the reasons, supported only by my empirical observations. I now know that the motor unit and electronics of the Victors put out RFI/EMI as the metal cage definitely acts as a Faraday Cage in neutralising and dissipating these when in a restricted enclosure. I can only surmise that when mounted fully 'nude'. http://i.imgur.com/jJoTuv4.jpg The electrical waves dissipate quickly into free air. The differences at any rate were quite subtle and are easily supplanted by the improvements made with the 'mass loading' onto the granite plinth. At any rate the question for me is now 'mute' due to the necessity for the grounded Faraday Cage in my new arrangement. http://i.imgur.com/msMbfXy.jpg http://i.imgur.com/UAEMFj7.jpg |
We may not have to rely on vintage DD turntables anymore. There appears to be a distinct revival.... http://www.monoandstereo.com/2016/01/technics-grand-class-sl-1200-turntables.html#more http://www.monoandstereo.com/2016/01/grand-prix-audio-10th-anniversary.html#more Could it possibly be that the Linn counter-revolution against the Japanese DD decks in the 70s was motivated by production costs alone.....❓👅 |
Henry, I think you meant "moot". The new SL1200 is very intriguing in that it seems to use a coreless motor, rather than the typical Technics iron core motor. (All Technics DDs, from the SL1200 to the SP10 Mk3, used iron core motors, albeit the one in the Mk3 bears faint resemblance to that which was used in the original SL1200, in terms of torque and the number of poles [24, in the Mk3], which would tend to reduce cogging.) The new motor would represent a potential significant improvement with respect to the old SL1200. Thus I wondered why (1) they are using the identical nomenclature for this new product ["SL1200"], and (2) they built it to look JUST like an original SL1200, as well. Since the price will be much higher than that of the original SL1200, even adjusting for inflation, this may or may not prove to have been a marketing error. Nevertheless, I am intrigued (because of the coreless motor), but I don't think this thing will blow away what we already own. |
And Dover, you probably should consider changing the electrolytics in the drive system of your Final Audio TT. Forty years is challenging the upper limit of electrolytic life, albeit if you indeed do use it "every day", that would tend to prolong their lifespan. I don't see any reason why you should fear that doing so would in any way negatively affect TT performance; in fact, if any of the originals are leaky, it would improve performance. |
