Lenco L75 and Mayware Formula lV
« on: December 25, 2019, 11:59:35 AM »
Today I removed the Lenco arm from another L75 I recently acquired from @Mushroom in order to perform the bearing upgrade to the arm .

So while the arm is off , I thought I'd try the Mayware Formula lV in it's place.

The Lenco arms mounting distance is 210mm . The Mayware Formula lV's mounting distance is 211.75mm . De-soldering the Lenco armwires from the top-plate allows one to loosen the VTA screw and lift the pillar directly out of the base . The Lenco arm base is large enough to allow a little wiggle-room required for the additional 1.75mm .

Please post some pictures of the bearing upgrade, keen to see how you fit it into the v-block space

I will @vleisman . I just want to try and aquire a bearing with a 5mm OD and 2.5mm ID . That way one does not have to take anything off the knife-edge bearing , making the mod completely reversible.

I have 2mm ID bearings , but not 2.5mm . NTN manufacture such a bearing .

If anyone manages to source these or another bearing in SA with 2.5mm ID and 5mm OD , please let me know , else I must import them .

I must say , the L75/Mayware combo sounds fantastic with the Piezo YM308 tracking at ~1.8g . No IGD , no sibilance , just solid beautiful full sound .

Are those the special audiophile-grade vibration absorbing Koo baked beans?

Got the L75 back in it's plinthe . I still need to cut a bottom and add rubber feet .

I'm still amazed at how good these old Lenco's are .

The plinthe needs a clean-up too - for now I'm just going to enjoy listening .
