| 3 New UBER Decks - Is this Turntable's SwanSong? 🦢 Halcro. I think that the numbers and green graph are useful provided their limitations are taken into account. Mean frequency....This is a good number to have. We are looking for 3150Hz, so nice and close to this is desirable. Raw frequency…... | |
| 3 New UBER Decks - Is this Turntable's SwanSong? 🦢 Yes.;The Yellow trace is a a long way away from the ideal sine wave, its pretty messy. This TT is not micro speed stable. As I implied before, on average it takes 1.8 seconds to complete a single revolution ( 33.333 rpm) so the filtered Green trac... | |
| 3 New UBER Decks - Is this Turntable's SwanSong? 🦢 Re speed stability. As has been noted, the numbers produced by the platter speed app vary from test to test. This depends upon how the tester placed the record on the spindle, there is a small amount of clearance, so the record can appear to have ... | |
| Who needs a Diamond Cantilever...? 💍 If I may, a question for Jonathan.Some cartridge designers use super short cantilevers. As the stylus tracks the groove it moves in an arc. With a short cantilever this arc has a very small radius. Would this cause an inter channel phase shift as... | |
| Technics SL1000 MK3 (SP10 MK3) performance/value VS modern turntables? @au_laitGood idea, I wish I had thought of pre and post recording. Unfortunately this hasn't been done. cheers. | |
| Technics SL1000 MK3 (SP10 MK3) performance/value VS modern turntables? rich121.Thankyou for clarifying things, appreciated. And yes, our hobby should be the total opposite of stressful.Cheers. | |
| 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... |
