| Vintage DD turntables. Are we living dangerously? FleibThe speed sensor consists two parts..., The sensor coils which are stationary and a toothed magnet which is attached to the platter.Sorry, I wasn't clear in my earlier post.Cheers | |
| Vintage DD turntables. Are we living dangerously? FleibMany years ago I decided to completely replace the platter on my SP10 MK3The new one consists of a trilaminate of acrylic on the top 15 mm of lead and then duralium.The duralium interfaces with spindle and spigots to the lead and acrylic kee... | |
| Vintage DD turntables. Are we living dangerously? Peter and Lew.Thanks for your interest in my upgrade. It's not really appropriate for me to promote it via this forum. Anyone interested can PM me directly or go to my krebsupgrade web site.That said, just a small clarification; during the develop... | |
| Vintage DD turntables. Are we living dangerously? RwwearMany years ago I made a leather chamois mat for one of my home brew TTs I purchased a car cleaning chamois from an auto parts store.A few dollars from memory.I agree with Banquo that the best results were with the suede side up.Dont know how... | |
| Eminent Technology ET-2 Tonearm Owners Chris.I can relate to the water in the air comment.Here in Auckland, New Zealand, it gets pretty humid in the summer months. Many years ago I was listening with a few Friends and we all commented on the sound quality being sub par. It was put down... | |
| Eminent Technology ET-2 Tonearm Owners Hi AllI have just finished testing a precision pressure regulator in the air supply for the arm.I replaced a Norgren B07-201-A1KG reg with a Norgren 11-818-101Findings in my rig...,Was there an improvement? Yes. Things were a little clearer, more ... | |
| Vintage DD turntables. Are we living dangerously? HalcroWe have been thru the thermal expansion thing already. As I stated some months back, with an aluminium chassis, the change in spindle to arm distance due to delta temp is very small. Dover is correct, it is no where near a "few millimeters"O... | |
| Vintage DD turntables. Are we living dangerously? RaulWelcome back, we missed you!Beyond core functional test numbers, I do not put a lot of stock into equipment specifications. I prefer to use my ears. As above... We do not listen to specifications.If we did, tube equipment for example, with it... | |
| TECHNICS SP10 MK3 POWER SOURCE / SPEED CONTROLLER Gentle people.I have, had a controller with the voltage selector. I bypassed the selector which was a worthwhile improvement. But obviously, do this at your own risk and put a clear warning note on the rotary switch showing that it is no longer ac... | |
| Vintage DD turntables. Are we living dangerously? Dover.yeah yeah we have all heard ( read ) the arguments extolling the virtues of BD,TD and ID over DD.My point was that a synchronous motor in a thread drive has local error correction and under dynamic loads it is in play (correcting) all of the... | |
| Vintage DD turntables. Are we living dangerously? DoverI have listed the time line of my upgrade development on another thread. There I outlined why I persisted with the SP10. To repeat. It's "drive " is intoxicating. Halcro has used a different descriptor for his TT-101 but he and I agree on the... | |
| Vintage DD turntables. Are we living dangerously? Dover.I heard the Final enough times at Warwick's to get a fix on what it did well and what it did not so well. Hearing it at your place only served to confirm this.re the amazing comment. Under the right circumstances I find my car stereo to be "... | |
| Vintage DD turntables. Are we living dangerously? Dover.You are quite correct. I do not provide any objective proof that the number of servo error corrections have been reduced by my upgrade. However since I know what the upgrade process entails, it is reasonable to conclude that this is indeed t... | |
| TECHNICS SP10 MK3 POWER SOURCE / SPEED CONTROLLER LewGlad that you are enjoying my upgrade.Re a controller for the SP10 MK3The motor unit has all of the infrastructure in place. Commutation and speed sensors.There are a number of quality industrial PMSM controllers that could likely work well. Th... | |
| Vintage DD turntables. Are we living dangerously? Aigenga.re unipivot arms.You raise an interesting point, different arm bearings may well show a difference in the graphs. (Arm geometry may also show difference, as BT argues.) That said, have any of the rigs recently listed by Halcro had unipivot... |
