Vintage DD turntables. Are we living dangerously?
Henry, On that last post, one would have to peer into the brain of a Victor engineer to find out why all Victor tts were not equipped with coreless motors. The motor in the TT101 is not only coreless vs the TT81, it also has considerably higher to... 
TECHNICS SL1200 MKII.......THE REAL FACTS
OK, so your Technics sounds better to you than did your "Sota, Rega, Linn, AR, Thorens, Dual". Each of those brands comes in several flavors (except for the AR). If you owned the low end of each line, your results with the SL1200 are not at all su... 
A Copernican View of the Turntable System
Henry, Agreed. Dissimilar materials. Spikes only work as diodes if one takes care to place them over vibrational nodes in the shelf material. These can be identified by tapping the shelf whilst moving a stethoscope bell across it so as to find pla... 
A Copernican View of the Turntable System
Dear Ecir (Brad, I think), Thanks for that URL but which feet on that page are you using? There are at least 6 or 7 different products shown. (This kind of troubles me because it makes me wonder whether the manufacturer has a real "philosophy" or ... 
Vintage DD turntables. Are we living dangerously?
Aigenga, I think what you wrote could also be termed an increase in "fluidity". In any case, what you wrote would be another fair description of what I hear with the L07D as compared to other DD turntables I have owned which use motors with iron o... 
A Copernican View of the Turntable System
Brad and Henry, I have found that small size cans of mandarin orange slices in water make excellent footers for my Lenco in slate plinth. I use 3 cans, tiptoes on the bottom of each can and a spacer on the top of each can so that the turntable mak...

PS. Yes, coreless = slotless. Just found a site that confirmed my impression. And coreless motors do not exhibit cogging. 
Vintage DD turntables. Are we living dangerously?
Dear Henry,The question you raise has also interested me from time to time. The internet is full of information on motors. However, much of it is written using jargon that is unfamiliar to me and therefore quite dense. But here goes my current und...

A belated response to Henry's question about the complexity of the SP10 Mk3 vs the TT101: There are no on-board electronics in the Mk3 save for the on/off and speed selector switches and wiring thereto and the brake solenoid. All the electronics a...

"Small ones" does not tell me much. Some electrolytic caps in solid state devices can have values as low as one microfarad and below. Such caps are tiny, but they are nevertheless electrolytic. If they are electrolytic it would seem to me they are... 
Vintage DD turntables. Are we living dangerously?
Hiho, FWIW, that's the first thing I noticed once I got my L07D up and running, an uncanny sense of "fluidity" (good word for what I hear), plus the L07D's signal to noise ratio seems to be unusually low, which adds to that same sense. The turntab... 
Who needs a MM cartridge type when we have MC?
Dear Dean, My first Acutex came with the Saturn headshell installed. When I foolishly tried to take them apart, the exterior frame of the cartridge body stayed inside the Saturn and the bare coils came out in my hand. It was instructive to say the...

Timeltel, The word in the eBay ad is "PuNtina", not "putina". 
Who needs a MM cartridge type when we have MC?
Dear Henry, You say you ordered silver leads from 2juki. The leads were poorly soldered to their cartridge pins. So you do have a legit complaint. But how does this make them "fake"? Fake would be a fair adjective, if the leads were made of someth... 
Who needs a MM cartridge type when we have MC?
Since the LPM320STR III is one of my favorite cartridges, I hopped right over to Italian eBay and bought a 420. However, I am a little apprehensive since all they show is the box. Does anyone know whether "puntina" = cartridge? The word would seem...
