My bought new Td 150 mk2, over the decades had developed a Verrry slow arm drop.
When it devolved to taking ~20 seconds to hit the LP... I decided to fix it.
Soooo I lightly oiled it (bottom off adventure) No disassembly though. Immediately the Lag was gone.
Lift dropped instantly Bounce the needle instantly. Toooo fast imo.
Lived with it for a decade or so, albeit I rarely played my LPs in the interim.
Today I decided to revisit it.
Disassembled the Lift Contraption entirely and to my chagrin, I found Zero damping inbuilt .
Just a stoopid/simple rod in a bore. No silicone, no chamber, no o rings , no seals, no valves ..Nada.. Nothing at all.
Seemingly not even any attempt at it
Sooo... Am I correct in assuming that Congealed oil residue is the only working damping on these contraptions?
PS; did refit with Phils' Tenacious oil as experiment (Hypoid oil sans the Sulphur smells, thick as molasses )
No noticeable difference.
I see that My version Lift is fitted to a series of Thorens TTs.
Are these All like that then ?
Just yesterday binned an old Cheap Automatic TT that had irrevocably seized from decades of Non use.
Even ..It, had a very nicely made Lift/drop damping device, a wee shock absorber thing which still worked.
Never ocurred that my Thorens was lacking such entirely. Or I would have salvaged it.
Hopefully I've missed something Basic and there IS a simple 'fix' ??
