Thanks nat. Thanks markse.
I have no argument there. The Lenco L75 arm headshell feels like a tin box. It's not even heavy!
The cartridge that I am now using on the Lenco arm, a low output Audio Technica AT-OC3, also vibrates when tracking high energy passages on stereo discs. The sound this vibration produces is of course passed on to the amps.
I think the heavily damped Kuzma unipivot will be (I wait with bated breath) the perfect foil for the iconoclastic Decca.
markse—I will do the wiggle test but need to gather up courage first
I did slid open the top cover for a peek inside. A bit of dust but no severe rusting or corrosion.
And yes I can take a photo but I need to charge up the camera battery first.
