| Direct drive vs belt vs rim vs idler arm Halcro/TonyI've just done the Halcro drop test of dropping the stylus on and off without adjusting the speed. The fall off in speed is minute. I would estimate it would take a couple of hours at least for the error to translate to 1 complete revol... | |
| Direct drive vs belt vs rim vs idler arm Halcro - I think your test methodology would prove that only turntables with error speed correction built in will pass. We know that stylus drag exists and should always set speed with the stylus playing. The question then becomes how significant ... | |
| Direct drive vs belt vs rim vs idler arm RichardkrebsYes I agree on moving away from which is best to what do we need.Mosins previous posts on motors used in various idler drives for example would indicate to me that you cant even put Garrard 301/401's in the same camp as say the EMT 927... | |
| Who needs a MM cartridge type when we have MC? Raul - I think everyone does think about what you say, but many do not try suggestions out. If I was a turntable designer I'd call it inertia. If I was a cynic I'd call it laziness.The main issue I have with the nude TT approach is that I believe ... | |
| Direct drive vs belt vs rim vs idler arm Richardkrebs - Interesting post. Could you please elaborate on a couple of points.Contrary to some opinions expressed in these forums, the servo does not intervene unless an external load causes a speed change. ( this assumes that the TT has been ... | |
| Direct drive vs belt vs rim vs idler arm Spirit of musicWhere are the specifications that suggest the Transfi has high torque.On the contrary, from their website -"Note1: The 9kg platter has immense inertia & will take a few seconds to respond to the control knob. Only very slight tw... | |
| The Lawyers Have Taken Over Audio Top end audio is struggling for survival and all you guys can do is bag people for trying to sell it ... I can tell you the money is in the baby boomers and they dont want to spend weekends trawling ebay and the local flea markets. They actually l... | |
| Best Amp for Klipsch La Scala Speakers? Xmas Gift DalecrommieJust curious.....when has Quicksilver Audio ever produced a 300b amp? Just sayin' :)http://www.artisanaudio.co.uk/Brands/Quicksilver%20Audio/Quicksilver%20300B%20Single%20Ended/300b.htmlMate, if you dont believe someone, do your homewor... | |
| Who needs a MM cartridge type when we have MC? Halcro - thanks and best wishes. Agree with Raul, but there have been seminal TT designs putting forward their goals clearly in terms of the record/cartridge interface. The Final's design was based on "Kitamura's believes that energy cannot be ign... | |
| Direct drive vs belt vs rim vs idler arm Mosin - no worries. The silk thread I use only seems to slip fractionally on start up, but the 20kg platter can be up to speed in less than 1 rotation, depending on how I tension it, which I think is pretty good considering the pulley is only abou... | |
| Direct drive vs belt vs rim vs idler arm Mosin - please re-read my post.I did not say that elasticity causes the belt creep. I said it is an assumption and that if the belt doesn't stretch then there is no creep.Mark Kelly's calculation of belt creep is : Creep = T/r x A/EWhere T is torq... | |
| Who needs a MM cartridge type when we have MC? Well then the answer to Lewm's question is yes - shape will affect resonance.You can mathematically model a proposed shape using fourier analysis, but the traditional method of measuring resonance is the use of accelerometers to measure the resona... | |
| Direct drive vs belt vs rim vs idler arm The belt creep that Mark Kelly expounds assumes the belt stretches and thins slightly, ergo if the belt doesn't stretch then there is no belt creep.Japan. Big and round. There are lots of ways to reducing or eradicating cogging, varying the ratio ... | |
| Direct drive vs belt vs rim vs idler arm Lewm - he didn't say elastic belt drive, he said belt drive. My silk thread "belt" does not stretch, the ac motor doesn't cog, and I dont get belt creep whatever that is. According to both the Timeline and KAB the speed on my deck is rock steady. ... | |
| Who needs a MM cartridge type when we have MC? Lewm - you should probably start with another thread on plinth shape.If you are embarking on a new plinth you should really start with a comprehensive project definition listing your requirements. What are you trying to achieve, what are the deliv... |
