I think that is the term , looking at my new thorens I see that in realtion to the top deck , the platter seems to go up and down a bit as it revolves .I think I read description as platter swim ? What would this indicate ? I have not tuned the suspension or anything yet .
thanks

That you bought the wrong Thorens? Just kidding.:D Interesting phenomenon. I'm curious as to the cause myself.:scratch2: Sorry I can't be of help...

well after running all evening it seems to have settled down to a very little "swim " , I'm sure a read somewhere what this indicates but... old timers disease ya know !

these are great for playing warped records. Just make sure you place the record with the warp facing the opposite way.

It cancels out...:D

Bifocals maybe? :D

trifocals !

A little bit of swim is probably not harmful but inaudible wow could potentially cause damage to your woofer. I would look to make sure that there is not excessive woofer motion. I would also suggest using a subsonic filter just to be safe.

I noticed the same problem with my Luxman PD-441 following a recent move. I trued the the sub platter with a small blob of Blu-Tak (sort of like balancing a tire) which resulted in a significant visual improvement. I suspect that the spindle(motor shaft) was likely damaged by my stupidity in leaving the platter on despite what I thought was bullet proof packing.

Make sure that the pulley or the motor shaft is not bent, and perhaps fiddle with the suspension.

You also might try rotating the outer platter 180 degrees.

I'll only add check the belt to DD's suggestion. For detailed instructions on setting up the suspension just go HERE (http://www.theanalogdept.com/susp_tim_bailey.htm).

Outstanding write up on tuning Thorens suspension with great step by step! This is the one that I learned from. :thmbsp:

Thanks guys , seems to have righted itself ? Maybe it just sank in with use ?
Those links are a black hole , I can see a long winter of fiddling ahead starting with the tuning and a new bottom cover . I do miss the interchangable head shell though , I am looking for headshells but I guess they are a rare and $$ beast.
cheers

The theanalogdept is a great site for a Thorens owner. I started over 3 years ago with a stock TD150. Here is where I am today, with a few more minor tweaks to come. I've already replaced the spikes with a set of Audio Technica feet since these pictures. Owning a table that is as tweakable (my own word) as the Thorens can be a Black Hole, but you are well rewarded with what they give back in performance.

Great looking TT ZB, you showed us that one awhile back, it's the one that got me fired up to build a giant killer, how do you like that arm?

I see we share the same platter mat at least ! Nice table for sure .I have a long road ahead from what I see over at the A.D. site but should be fun . A spare headshell is high on the list , so if anyone sees ones give me heads up .
cheers

Love the arm, DD. Changing out the stock end stub & counterweight for the michell technoweight makes changing cartridges a lot less stressful. I tried three or four different carts on it, and then found the match I was looking for with an ADC XLM Improved MKII.

I really like these mats, not only do they look good but they live up to what the manufacturer says you should expect from them.
