| Turnable database with TimeLine I had a chance to experiment this evening. I used some rubber shims to constrain the sub chassis on my turntable in the horizontal axis. My Sota has the motor fixed on the main chassis while the tonearm and platter float on the sub chassis. First,... | |
| Turnable database with TimeLine Hi Harold,Cool video. Very cool turntable and tonearm. I watched the video on my iPad and I could hear the WOW. I was supposed to be able to hear it, right? I think it was most pronounced when the stylus tracked over the wave in the record rather ... | |
| Turnable database with TimeLine Maybe I am pointing out the obvious here. Our ears don't care about average speed. Our ears hear the minute variations in speed. | |
| Solving the THIEL CS 5i's - vs- CS 7.2 Debate I have had the Thiel CS6's for almost 7 years now. I love the sound of them. I moved up from the CS3.6's and found it to be a significant upgrade all other things being equal. I use a Pass Labs amp with MIT cables. I got no complaints about the so... | |
| Turnable database with TimeLine One other thing: Look at the specs of most turntables. The WOW & Flutter measurements of most high end tables all seem to be around +/-0.02% to +/-0.04%. Most of these very nice turntables here are showing excellent speed settings to within 0.... | |
| Turnable database with TimeLine Hi Halcro, let me explain something about motors here without the added detail of charts and graphs. A motor runs at a constant speed to the casual observer; but if you take a much closer look you would see that the motor armature actually speeds ... | |
| Turnable database with TimeLine I'm not sure it has been confirmed that the newer Timeline devices have 6 flashes per rev. At least the ones everyone is using seems to have just one flash per rev. Regarding tachometers: most today and even the one in your car uses either optical... | |
| Turnable database with TimeLine Hi Lewm,How can micro variations in speed due to groove modulations be measureed with a laser light that flashes just once every 1.8 seconds? The answer is that it cannot. The Timline gives you average speed- that's it. Don't try to read into it a... | |
| Turnable database with TimeLine There are two subjects here: 1) How well do the differing turntables hold speed to exactly 33 1/3 rpm? 2) What is the effect on platter speed during heavy groove modulation?Subject 1 is being answered with the Timeline device testing. And the Time... | |
| Turnable database with TimeLine I think the confusion lies in trying to use the Timeline, which shows average speed over any period of time, to evaluate momentary, micro-variations in speed due to stylus drag. The timeline can only infer that speed is varying once the stylus is ... | |
| Turnable database with TimeLine I graduated from college and started working in Aerospace Engineering just as the WWII generation was starting to retire. I had the privilege of being mentored by engineers that started working just before and after WWII. This is the generation th... | |
| Turnable database with TimeLine Halcro, My test record that I use for the iPhone app is also flawed. The record hole is off-center so I filed the hole open a bit and I must center it as best as I can on the platter. I get differing Wow&Flutter measurements (between 0.06% dow... | |
| Turnable database with TimeLine A DC Motor is a simple device. The speed is proportional to voltage input and load. If the load increases then the speed will drop and current will increase. My Sota tt has a simple power supply and DC motor. It has a trim pot for fine tuning spee... | |
| Turnable database with TimeLine Well, the Timeline is a strobe; but I do not say that with disdain. It is just a fact. It is a very precise strobe with reported 0.0002% accuracy. As with any measurement device it must be used properly. The results must be interpreted properly as... | |
| Turnable database with TimeLine Hi Peter,One thing I noticed on a couple of your videos, as you had mentioned, the red line is sometimes shorter. Do you see this when watching it live? I suspect that the occasional blip in the red line on the video is due to the shutter speed of... |
