Default Golf Balls cut in half to assist turntable suspension?

I aquired an older Technics SL-1400 MK2 turntable. I suspect it is better quality than my current older Technics SL D212 turntable as it weighs about 3 times that of the SL D212. I had a dealer peruse it and he informed me the suspension springs were gone. He and myself tried to get replacements but Technics do not stock them ( 1979 vintage). I have tried all the web turntable repair places and no , no one has them used or new.

I was wondering if those tweak ideas such as golf balls cut in half may improve the situation?

Any opinions?

Maybe you can search "compatible" springs from another maker, Linn?
Do you play golf?

When I used to take things apart in my youth, I remember chopping a golf ball in half once, and the inside was packed with tiny strands of compressed rubber. They expanded out as soon as taken out of compression, and I don't see how this would work for a suspension system.

The whole is better than the sum of the parts, though!

I would either try the half squash balls as has been suggested, or remove the springs and lock down the suspension to make it a solid plinth TT, then use a sandbox or innertube for solid or suspended floors respectively.

The SL1200 isn't a bad TT if you replace the arm, but I'm unsure of the 1400. Also, get a bottle of bearing lube for the SL1200 ($4), which is a current part or available from www.kabusa.com and lube the bearing good. Needs to be done ever 12 months or so, and no one ever does it. I nearly binned an SP10 before I lubed it, now it's quiet like a mouse. Not a pink one.

I assume he meant squash or tennis balls. Golf balls would be a chore to cut in half, not to mention the lack of suspension they would offer.

I'm curious as to how a turntable spring expires, and how a dealer would diagnose such a fault. Not to put too fine a point on it, I don't see any way in which a turntable spring could fail. We're not talking about tank suspension springs that are hammered by being driven at full tilt across a field with shell holes, we're talking about a suspension that is treated with reverence and prayed to each day (oh God, please don't let me scrunge the stylus).

You could get a set of tuned (i.e. matched frequency) springs from another TT manufacturer, as suggested above.

They'd have to fit, of course, so check the diametres, screws etc on the subassembly.

A parts shop may stock this stuff too; bet you it would be cheaper than the branded equivalent

Talking springs

greetings audio addict

chuck the springs and invest in a decent isolation platform.
If I remember right the springs work similar to the SP10 MKII/Obsidian base combo in that their function is to filter out low frequency feedback (supposdly tuned to 16hzs) but nevertheless detract from an otherwise perfect TT.
A diy platform is easy and you can use the balls there. I used 6 "super bounce" plastic foam balls cut in half with 3 sheets of 16mm mdf 4 AT605 feet (can use 4 halves instead if feet not available)and for fun a sheet of glass and 4 self made alu spikes . Will eventually take pic (if anyone interested) and the best part was it won instant WAP when finished in black.
End result no feedback/vibration of any kind at all and believe me with a Micro BL 77 you will hear it if it is there.

All other attempts never got to first base. (mind you if I added some flashing leds to the bottom it could be miscontrued for an UFO)
regards
