Rega Apheta 3 on Rega Planar 8:  Any idea on screws torque values ?

II asked my distributer to check with Rega.

In the meantime, as advised above, I will close it very gently just so it does not move.

Rega does sell a torque wrench. It's $275 USD. It's included with their Aphelion 2 cartridge but available separately on Music Direct and other audio websites. I don't see it listed on the Rega website however.

Just talked to Rega. Apheta 3 is also 0.4Nm.

instead of spending $275, just follow dover's advice and it will be a lot cheaper without any other compromise. 

second instruction of that cartridge somewhat amused me about cartridge bolts... are the wires of the cartridge that badly exposed and lose that they can potentially reach mounting bolts??? that's weirdest design perhaps.

275$ is way too expensive but 99$ for a Hazet is reasonable ...
