LENCO High-End Modifikations

High-quality Lenco modifications for optimal sound performance


You’ve come to the right place for exclusive high-end modifications for Lenco models L70, L75, L76, L76s, L78, L88 — and now also for the B52 and B55.
These technical upgrades deliver a noticeable improvement in sound quality thanks to reduced friction, greater clarity, and enhanced stability.

The modifications are known as the TJN-mod and Lenco bearing mod. I have further developed these concepts by incorporating my own ideas and refinements to achieve even better results.

Available Modifications:

Replacement of the idler wheel spring with a stainless steel weight

(Known as the TJN-mod) - This provides a more stable rotation and reduces vibrations.

Central bearing modification (Lenco bearing mod):

  • Removal of the original thrust plate and Seeger ring

  • Replacement with a PEEK thrust plate and a silicon nitride ball (instead of the standard 5 mm steel ball) - suitable for “double platter” setups!

  • Mounted on a 1 mm silicone pad, fully sealed with a 5 mm aluminum plate and flange - ideal for “double stacked” applications

  • The bearing is fully oil-filled, resulting in extremely low friction and outstanding stability

Stabilization ring on top of the central bearing

  • Made from a heavy-duty metal ring for extra strength and precise guidance

Bitumen damping on chassis and platter

  • Reduces resonances and ensures a cleaner sound reproduction

Damping of the idler wheel shaft with Teflon tape

  • Further reduces mechanical noise and vibrations
