    When I was at the last BAAS even on Dec 6, I believe it was there I heard the best explanation of 'to clamp, or not to clamp'.

    Basically, some clamps can reduce the noise of a turntable and help flatten the record. Other turntables that send a lot of vibration up through the spindle and can make a record sound worse when clamped.

    I guess it is all just trail and error. but my concern would be increasing resistance on the bearings and the belt which could slow revolutions per minute down.

    which on my rega maybe wouldn't be a bad thing, if it just slowed it down. i've had the feeling, especially on the tracks close to the label, that sometimes it speeds up.

    there is probably a way to test the speed isn't there??? isn't there???

    Vinyl engine has downloadable and printable strobe disks. At least one fits in the label area of an LP so you can check the speed while playing something.

    You wouldn't be able to slow down the Rega motor without changing the frequency of power you feed it. That's where the TT PSU comes in. If the frequency was off, the turntable would be off. I believe a strobe would also be off at that point, so the Strobe Disc would appear correct even if the speed was incorrect.

    Over at AK, I read a post where someone recommended running a strip of tape around the subplatter to increase its diameter and therefore slow it down.

    aA this will correct the speed of the table as it did for mine. The explanation of how it works is that it is machined slightly larger compared to the stock subplatter. Some sites suggest putting a layer of tape around the subplatter which would also increase it's size to lose that 1% speed increase Rega's have in this country with the 60 hz line frequency.

    Oh and like 02audionoob said in the previous post I just read.
