Vedr. olie er der denne tråd hvor Robbie Sheridan (der er ingeniør, med daglig omgang med den slags) bliver citeret.
viewtopic.php?f=558&t=8415 Han er i øvrigt meget inkarneret Thorens mand.
Jeg havde en længere snak med ham via FB, hvor han fortalte om hans research.
Det korte af det lange, han anbefalede Renac ISO68 til glide og langsomt roterende lejer. Og Regin Z22 til motoren.
Lidt af dialogen her under:
Hi Tonni, The Thorens manual for the TD124 states that the correct oil for the motor and main bearing is Caltex Regal or Texaco ROB. The correct oil for the stepped pulley and idler is ROG. I have contacted Caltex, Texaco, and Chevron, and they have confirmed that Regal ROB is turbine oil with Rust & Oxidation inhibitors. The B puts it at ISO46 grade, so any modern T46 is pretty much identical. I am using Regin Z22 fan oil which is derived from Unocal turbine oil, but has anti-gumming agents and is made for bronze bushes in motors up to 1/4 horsepower. It works very well. The Regal ROG is turbine oil with Rust and Oxidation inhibitors. The G puts it at ISO220, an oil that is no longer easily available. I couldn't find it anywhere online so had it blended in a specialist lab in the UK. It is much thicker than the T46 oil and I suspect that it was chosen for its ability to dampen out some of the noise from the pulley and idler that seem to be a problem for many people, rather than its lubricating properties. By coincidence, I'm a turbine engineer by trade and so digging around for the correct information wasn't too difficult. I can get some T46 easily as well. When I started working on the TD124, I had a look at several online forums and could see that most people were guessing the correct oil or just using trial and error, but most were using the same oil everywhere on the table. The only person that I know that uses thicker oil on the pulley and idler is Jaap. He uses Renetac 42, a sticky oil made for bearings and slides. It is now obsolete but the modern equivalent is Renac ISO68. This is less viscous than the T220 that I had made, but it is sticky. It is similar to EP oils that you use in gearboxes and so on. Many guys are using SAE 20 single grade motor oil. This has similar viscosity to T46, but is not the same oil. I originally used SAE 30 additive free single grade oil, but it is a little too thick for the motor bushes and doesn't perform very well. I think that you'll find that most oils will work to some degree, but Thorens spent a lot of R&D time getting the noise levels on the table as low as possible, and would have selected the oils carefully, so they're good enough for me! Sorry for the long reply but I just wanted to assure you that I have done the research and correctly identified the modern equivalents to the original oils that Thorens used, something that I was surprised that nobody else had already done. Regards, Robbie.
Håber det kan være til hjælp i de små hjem. - Og tænker de olietyper også kan bruges til mange andre grammofoner...
