SME release new Garrard 301
There are 2 things going on @fsonicsmith There is a friction brake on the inside of the 301/401 platter which stops the rotation as soon as the machine is turned off. At the same time, the idler is moved away from the pulley and rim. See here: https://www.youtube.com/watch?v=N_nRh_WYh74 |
fsonicsmith: Hi, all that noromance has stated is true. Having said (written:) that, I’m at a loss for why your platter is immediately coming to a stop. The break will slow it down but even with the stock platter which weighs what, say 5-6 lbs if memory serves, it still takes a few seconds to come to a complete stop. BTW, I’m not referring to the eddie brake here, I’m referring to the platter brake which engages when the turntables on-off switch is placed in the off position. A little brake pad (felt pad on a lever) comes up and meets the inside of the rim and slows it via drag. The idler should disengage when the 301 or 401 is off (using the mechanical switch). If you are using your PSU as the sole control system, i.e. leaving the physical switch on the 301 chassis on and turning it on off using the PSU, that would most likely explain your resulting platter action. If that is the case I might suggest this is bad for your idler wheel and may, if it hasn’t already done so, result in a flat spot on your idler wheel. |
fsonicsmith: Ah-ha, I missed this the first time I read your response: “At least on my 301, the platter will not spin freely-the idler wheel-mine is the Audiosliente btw-is always engaged against the inside platter rim. ” This is the culprit! I don’t know if the unit has a fault or if someone purposely disabled some of the linkages but I would say this is a sure fire way to create a flat spot on your idler wheels rubber periphery and hence noise in the form of rumble. I can tell you with confidence that this is not the way the 301 or 401 was designed to behave. |
@audiofun Thanks for looking over the cave. I love the Decca. I have another Garrott Grey Export. Be interesting to hear the LDR on the other arms especially the Kuzma but all that is out of my willingness to spend that kind of money. It all goes on enormous property taxes and healthcare insurance payments. |
