Thorens had a very heavy weight for their turntables. I believe it was around $300.00 or so. The Project heavy weight is around $100.00 and comes in a neat wooden box and is around 700-800 grams. I used mine for a couple of years but now switched to the HRS weight which is a little over 380 grams.
Time to Clamp Down
I have several record clamps that I use with my turntables, but I have a Thorens TD-160 with a spindle that is too short for a clamp to 'grab'. I have a very heavy turntable/record weight that probably weighs around 24 ounces, quite heavy. I would have no problem using that on one of my direct-drive tables, but I am skittish about using it on the belt-drive TD-160. Logic tells me it would put an extra-heavy load on the motor, causing undue wear.....is that a valid concern or not? The spindle clears the record just enough for this monster weight to work and right now it's my only option.
