Oracle Alexandria - time for new springs?

Hi,

I recently went through and readjusted the suspension on my Oracle Alexandria turntable according to the manual. When set up "properly," two of the three spring covers no longer fit into place as the springs are protruding too far above the deck. Everything sounds fine but this thing with the spring covers is a real drag. I bought the table used and it came with the Sumiko MMT tonearm and [ugly] head shell. I am using an older Sumiko Blue Point cartridge. I am wondering if this is a sign that the springs are bad and need to be replaced. I've always assumed that it has the correct type of springs since the tonearm is standard; maybe not. Anyone have any experience with, or ideas about, such suspension table problems?

Thanks,
rickk

Rickk, I doubt that the "white" spring is the problem. Have you "re-threaded" the plastic ring supports? Mine end up at about 1/4" from the top of the spring, leaving only a bit of the spring exposed on the top. Do the springs look like they are elongated?
I would go through the whole exercise of re-threading the the plastic ring supports and see where it ends up then.
BTW, if the platter ends up too high, the belt might not align properly on the motor spindle, so not higher than 11/32" is a proper precaution. I feel that the best position is really 1/2 way of the platter's travel between hitting the top and the bottom.

Rickk, are you sure that you have the proper springs in the proper location? They are colour coded to distinguish which go where, since the load will be different in each location.
The strongest spring is Green and should be on the right suspension module, a Yellow spring is slighly weaker and should be installed on the left rear and the remaining Grey spring on the left front.
I just finished doing the recalibration of my Alex III with Rega 300 and had no problems with obtaining the 11/32 inch clearance. The springs (table) are about 14 years old.
Salut, Bob P.
