| Technics SL1000 MK3 (SP10 MK3) performance/value VS modern turntables? "…..I may wait on the Krebs for now" congratulations Dover, you achieved your objective. When I released my upgrade to the audio community, I did it because I was excited by the prospect of sharing with fellow SP10 owners what could be realized ... | |
| Help - Scroeder CB-9" tonearm - anti-skating setting issue HiIs the distortion more prominent in one channel or across them both?This could be a clue to the problemAgain, a possibility......Bad in the left channel, too much antiskate, Bad in the right channel, too little antiskateBad in both, incorrect al... | |
| Help - Scroeder CB-9" tonearm - anti-skating setting issue Hi. This could be an alignment issue. Distortion rises dramatically with all of the curves past their inner null points. What cartridge alignment curve are you using? Cheers. | |
| Help - Scroeder CB-9" tonearm - anti-skating setting issue Hi. I own a CB-L. I'm with stringreen, it tracks pretty much anything on any antiskate, setting but is awesome once dialled in.Have you checked if the TT itself is level? Cheers | |
| Fuses in the 3 speed SME PSU @noromance re your idea of masking tape on fuses.... I considered this, but was concerned about long term drying of the adhesive. I used Teflon plumbers tape, tightly wrapped around the glass. Nice uptick in performance.Cheers | |
| Direct Drive vs. Idler Drive vs. Belt drive @totem395 Yes it goes without saying that the drive can manage an apparently stationary dot over 1.8 seconds. I was referring to a longer time frame, say a complete side of an LP. To me it doesn't really matter if the dot has drifted a little afte... | |
| Direct Drive vs. Idler Drive vs. Belt drive Mike.Many thanks for the invite. There is a little problem of distance however, since I live in New Zealand.I do not disagree with you at all re the signature of "most" DDs. I spent 15 years whittling away at my mk3, little by little mitigating th... | |
| Direct Drive vs. Idler Drive vs. Belt drive An update to my last post. A point I didn't make clear. The change in angle between the rotating field and the rotor due to dynamic changes in load is a momentary change in platter speed. It is measurable and audible. Over time the average speed ... | |
| Direct Drive vs. Idler Drive vs. Belt drive Lew.The problem is not the motor it self making noise. This assuming the designer has used a good one. The problem is the interaction of the controller/ motor/ platter feed back loop.IMO the designer should use what I call a very tight motor. I me... | |
| Direct Drive vs. Idler Drive vs. Belt drive Mijostyn.Correction to my earlier calc, for those of you looking at my numbers.The original distance would be 4.63mm, where plus 10mm gives a 10 fold reduction in field strength. Still a physical impossibility. Apologies, for my typo. Cheers. | |
| Direct Drive vs. Idler Drive vs. Belt drive mijostin I would offer the counter view. It is far harder to build an acceptable DD than BD for the reasons I noted earlier in this threadFurther with respect to the distance from the source, as you say the inverse square law applies. Double the ... | |
| Direct Drive vs. Idler Drive vs. Belt drive In a synchronous motor the rotor lags behind the rotating field. This angle changes with changes in load There are subtle differences between motors, even with apparently the exact same build. This results in slight differences in this lag angle f... | |
| Direct Drive vs. Idler Drive vs. Belt drive has2bePeacecheers | |
| Direct Drive vs. Idler Drive vs. Belt drive has2beI was merely (re)stating an inherent advantage of a DD design with respect to its bearing, after all the OP has asked this....."I'd like to know your thoughts on the strengths and weaknesses of each drive system"I did not say that overall DD... | |
| Direct Drive vs. Idler Drive vs. Belt drive Yes, this is an advantage of a DD drive that is often overlooked. There is no horizontal force induced by a belt, thread, tape or idler wheel.There is a toppling force if the thrust point is at the bottom of the bearing but this should be easily a... |
