"Agreed. Your listening impressions of the TT101 as compared to the DP80, both with your upgrades and plinth, would be very informative."
But I can't help thinking.....perhaps understandably biased...👀❓
Vintage DD turntables. Are we living dangerously?
I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.

Yes best-groove.....is me 🤡 Just demonstrating how the Victor DD turntables are able to maintain absolute speed consistency under the dynamic loads (including 'stylus drag') of up to three cartridges at the same time. Haven't seen that test with the Timeline successfully done with any other turntable..... But I would like to.....👅 |
Technics claimed the SP-10MKIII would maintain speed with up to one thousand tonearms tracking at 2 grams each. I'm aware of that claim and would love to see it demonstrated....👅 But seriously....I've seen claims by the new Monaco DD about its speed accuracy surpassing measuring instruments... I've also seen the VPI Direct Feickert Speed App test published by Fremer which didn't appear so 'perfect'? Regardless of 'claims'....there is a difference between 'speed accuracy' and 'speed stability'. It would be nice to see any of the SP10Mk3 owners out there with 2 or more tonearms, post a video to YouTube showing the behaviour with the Timeline. It would also be nice to see the NVS, the Monaco, the VPI Direct or any other vintage or modern DD pass this test. Claims are not worth the time of day.... |
Richardkrebs, Actually I would be surprised if any of the flag ship DD TTs from that era failed this test. I too would be surprised....but I still have not seen any videos subjecting any other turntables to the Timeline test with two or more tonearms/cartridges playing then NOT playing as per my video. Despite what anyone may think about the Timeline....this test displays significant information about the speed correction facility of the turntable under test. For instance my TT-101 is not as 'perfect' as the TT-81 under this test....The Timeline moves 2mm from start to finish 😱 For years, there have been promises here, that videos would be uploaded....but nothing appears. Surely you could do it richardkrebs and Peter...? For Peter, it can demonstrate the relative performances of the Denon DP80 and DN308. best-groove, The ability to turn a heavy platter at the correct speed has little to do with how a turntable is able to maintain speed under 'stylus drag'. |
Lew, Mikey has used the Feickert Platter Speed App to test his turntables for years. Just buy the test disc directly from Feickert http://www.feickert.org/index.php?id=16&L=1 And download the free App to your phone or iPad. The only problems I have found with it over the years is:-

For those interested,,,,,HERE is a video of the TT-101 with the Timeline and three tonearms to compare against the previous video with the TT-81. And HERE is the Sutherland Engineering video demonstrating the Timeline on a belt-drive turntable with a massive platter. Notice how the massive platter is slowed under the stylus drag of just ONE tonearm.....😱 |
Thanks Peter, Finally someone with the 'guts' to post a Timeline video rather than just 'talk' about it 👅 I applaud you...and good luck with your quest in reviving these vintage Japanese DD turntables. I have still seen no evidence that any of the modern DD decks can equal (let alone exceed) the performance of the great Japanese decks of the Golden Age.... Regards Henry |
Btw, who told you that the TT-101 is so " superlative " as you think because that's a total misunderstodd by your self or the one that told you?Uhh....let's see.... Apart from me and Lewm, there's Audpulse, HiHo, Aigenga, Thuchan and someone called Harry Weisfeld who wrote in 2014 I have a Kenwood LO-7D, a JVC TT101 (best of all of them), MS DDX-1000, an SP-10 Mk-2, etc. All are wonderful.....The TT-101 inspired Harry to design the VPI-Direct which, together with the $105,000 Techdas AF 1, are still the only A+ turntables on the Stereophile 'Recommended Components' List. @best-groove you even do not own those Technics.And Raul does not own a TT-101. Nor has he even heard one. A few years ago he bought a Victor TT-71 and because he has a 'need' to have the 'best'.....he declared the TT-71 better than the TT-81 and TT-101. He has never even heard the Denon 100M which he continually praises based on its specifications. Ask Thuchan how the Denon 100M (in his bedroom system) compares to the TT-101 in his main system.....😎 |
every enthusiast pushes his idols and his ideas forward I suppose There is nothing offensive in doing that..... But Raul is almost alone, in consistently denigrating other equipment and other contributors’ systems. Whether it’s cartridges, tonearms, turntables, phono stages, amplifiers or speakers......he has expended almost as much energy in these Forums, on his subjective negativity and personal vitriol, as on his (often) valuable positive insights. And that IS offensive to many of us.......🤔 |
Dear Raul, If you heard no differences between the TT-71 and TT-81....then something was very wrong. Either the TT-81 was faulty, the system it was connected to was not revealing or you are simply unable to hear discriminately 🤔 The differences between the TT-81 and TT-71 are far more marked than those between the TT-81 and TT-101 starting with the bi-directional servo control which is a patented breakthrough in DD technology and is the reason that the Yamaha GT-2000 (which uses the same Victor bi-directional servo motor) is so desirable. |
Jp, Hopefully you can make sense out of what Banquo managed to find...? I can only add that all of Victor's other turntables have PLL controlled motors but only a few (TT-81 and TT-101) include 'bi-directional servo-control' in their descriptions. If what you say is true about all PLL servos....why do you think this would be? |
You are totally wrong. From where you learned or I have to say ....) used Yamaha motors not JVC motors both are way different and measures different: 75db against 85db in the Yamaha. Wrong..... As only the Japanese can do, it was a co-operative effort designed by Yamaha in conjunction with Micro Seiki using a motor and motor control electronics from the Japan Victor engineer who designed the motor and motor control electronics for the TT-81. Mostly Micro Seiki mechanicals and Victor electronics. The 71/81 came with coreless motor, you have a misunderstanding. Wrong......
Sigh......so much mis-information |
Great news Chak...🎉 There is a regulation described in the manual for altering the STOP function to match your platter mat +LP. I had my Tech do it for my lightweight Victor Pigskin mat which is far lighter than the standard Victor rubber mat with which the turntable normally arrives. And having the platter 'check' with a slight backwards movement when the STOP button is pressed...is considered normal. You're a lucky man.....but there are no guarantees for the future. You'd be wise to blow-out all the old solder joints and do them all again as I did, if you wish to sleep peacefully. |
You can use the CU-180 but I don't know if there's enough adjustment available for such a weight...? If that doesn't bother you...go for it. I was more concerned with the weight on the bearing 🥴 No pulsation coming from the electronics on either the TT-101 or TT-81. Is it true that no lubrication needed for 40 y.o. unit ?Do you trust the Victor engineers....? I do 🤗 I've never lubricated mine. Just last week there was a soft drone coming from the platter once every revolution so I saw that the outer platter was too close to the fixed surround. I opened it up, turned it upside down to access the control screw in the base and turned it clockwise. If you turn it too much the motor won't turn at all. If you back it off from there a bit....the motor will turn clockwise, stop, turn anticlockwise, stop, turn clockwise etc etc. Back it off a bit from there....... Goldilocks.....😃👍 No more murmur... |
