| Who needs a MM cartridge type when we have MC? My main issue with wood is not the sound, its the dimensional stability. I worry about warpage or movement over the years after spending all that time making it. What you could do is rout some squiggly lines underneath and fill them with hotglue, ... | |
| Who needs a MM cartridge type when we have MC? Timeltel - I have a good friend who has worked through several plinths. Slate rings, panzerholz was dead and lifeless. His latest trials are going lighter, using a sheet of ceramic insulation ( rigid, easy to cut and no energy storage ) with an al... | |
| Direct drive vs belt vs rim vs idler arm Lewm - As in my earlier post on 12-30-12 belt creep is inversely proportional to the elastic modulus of the belt. Creep = T/r x A/E where E = elastic modulus .... Mark Kellyif a belt is inelastic, then E = infinity, and the creep is infinitesimall... | |
| Who needs a MM cartridge type when we have MC? It's not easy to bash the record, hold the strobe and camera with 2 hands.I have to borrow the timeline again - none in country - local audio shop has the only one which I borrowed last time. | |
| Who needs a MM cartridge type when we have MC? Hey Halcro - wanna try this on your Victor 101 ?http://www.youtube.com/watch?v=lwugFlbCOwwI've recorded the KAB speed strobe on my Final Audio Parthenon VTT1 thread drive TT while I bash the record with my knuckle.Anyone else want to have a go - I... | |
| Direct drive vs belt vs rim vs idler arm OK just for fun here's something to try on a Linn/Oracle/Clearaudio...take your pickhttp://www.youtube.com/watch?v=lwugFlbCOwwI've recorded the KAB speed strobe on my Final Audio Parthenon VTT1 thread drive TT while I bash the record with my knuck... | |
| Who needs a MM cartridge type when we have MC? Halcro - I agree with you, but would also add that you dont need the Timeline to tell you the speed is out on the Transrotor. The piano sounds awful - slow, turgid. Its not a good example of a high inertia deck, I suspect inadequate power supply/m... | |
| Direct drive vs belt vs rim vs idler arm RichardkrebsCan you please review the video again.From 0-24 seconds you can read the 33 quite clearly, but the 33 is moving forward and back, it is not stable.From about 57 seconds on - he now has a constant load on the platter. 33 is unreadable, ... | |
| Direct drive vs belt vs rim vs idler arm Video of Technics SL1200 - looks to be running too fast. The "33" keeps lurching forward and then slowing, repeatedly. It is non linear, like it's hunting or slewing around. Watch closely. | |
| Direct drive vs belt vs rim vs idler arm Yes I agree, thats pretty much what I proposed for testing to quantify the variation between that minimum and maximum drag levels and the impact of a piece of music in total...I think you misread my syntax ( no pun intended ). ("how consistant" , ... | |
| Direct drive vs belt vs rim vs idler arm Mosin - Absolutely right, I used mass loosely. I read somewhere the EMT idler has a platter of 5.5kg ( same weight as the copper mat on my deck ) but due to its weight distribution ( 16 & 1/2" platter ) is the equivalent of a 50kg solid platte... | |
| 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 ... |
