Congratulations! I bet it sounds as lovely as it looks.
I bought a Lenco L75/S this past year, and am very taken with that idler sound, even stock 9the arm is picking up some noise, though). The plan is to make a heavy CLD plinth with scrap plywood and MDF in the garage, mount a Grace or Rega arm on the plinth (fingers crossed this will eliminate the noise from the stock arm, which I believe it is picking up either from the top plate or being near the motor with poorly shielded wire). Once I get it sounding to my liking, I will make a proper one with quality wood.
Here's to that amazing idler sound! Whoot!
