Vintage DD turntables. Are we living dangerously?
Dear Peter,Forgot about the rotor, which would be a fixed to the bearing/spindle assembly.  Thanks.  My Kewood L07D is built like that as well, perhaps this is common to all coreless motors that more or less copies of the original Dual coreless mo...

Yes, the UNI is "pricey".  My only beef about cost is that, at that cost, it does not allow measurement of P2S with any accuracy.  When I brought this up, after purchase, I was offered the opportunity to buy an accessory which fills that void. How...

PBN, Was reading your instructions to Aigenga with interest, since I think I may have a go at cleaning and lubricated the bearing in my unit, once I get it back.  Seems to me that loosening the plug, which I assume means turning it counter-clockwi... 
TTW turntables
On a business level, he seemed to feel, or he wanted us to think, that he could not make a profit while also keeping up his high standards for materials and machining.  He refused to compromise on either, or to lower his prices, and so chose the o... 
TTW turntables
I think they are still in A business, just not the audio business. You might try to contact him through his "other" business, but, sorry to say, I do not know the name.

My point was not about whatever is the "correct" geometry for a DV505/507, because I don't know what that is, except it's likely to be at least close to Stevenson.  My point was that twisting the cartridge/cantilever in the headshell such that the... 
Question for you Denon DL-103 folks
Just to be clear, SMC, you are referring to the (vintage) Moving Magnet cartridge known sometimes as "M20FL Super"?  Just wondering.  That's high praise for such an unpretentious cartridge, but I don't doubt you at all.

ps68, You've independently hit upon exactly the reason I went off on a craze over these vintage dd turntables.  In the end, the better ones are the best bang for the buck.  Plus, the drive and rhythm that they can impart to music are addictive and... 
Is there advantage to balanced phono-preamp
I owned an Ayre P5Xe-mp, and selling it was a mistake.  It was great as a spare and as a second phono stage for MM/MI.  So, I second your nomination.

Thanks for the offer, Peter.  I sent you a PM.  Just as an aside, isn't silver oxide a perfectly good conductor, which is partly why to use silver?  I know when Bill Thalmann worked on my DP80, he replaced all the OEM transistors with new ones, on... 
Is there advantage to balanced phono-preamp
CLeeds, Please note that I used the word "usually" when describing the cable needed.  You've pointed out the cases where one would do other than the usual.  I was trying not to overwhelm Brrgrr with details. Thanks.You wrote, "For example, some ba...

JP did a lot of work on my TT101.  We're still debugging it, or I should say that HE is still debugging it.  More anon. 
Is there advantage to balanced phono-preamp
Whether it's a moving coil type or a moving magnet type or any of the variants thereof, the signal comes off a coil of wire.  At either end of the coil, the signal looks the same, except for its being opposite in phase.  So, a cartridge is an inhe... 
Parasound Halo JC 3 vs Whest PS .30R for the Lyra Delos
Dear Mark,  Am I correct in thinking that you assume your Whest phono stage uses balanced circuits?  I ask, because to the best of my ability to investigate it, back when I myself was in a buying mode, the Whest is not balanced.  It may have XLR o... 
Tonearm recommendation
To re-enforce what Dover said regarding the DV tonearms, I had the experience of mounting a cartridge in my DV505 using Baerwald, which requires the cartridge to be twisted inward with respect to the long axis of the headshell.  It was surprising ...
