The main issue with the Lenco tonearm is that it sucks. It's a piss poor implementation of a knife edge bearing with a tuning fork substituting for a wayrod and a doomed to fail tension wire suspending the back stub. The LH consensus effective mass for the L75 tonearm is 22 - 24g which makes it incompatible with too many common MM/MI carts. Other than the too thick stock wiring that very often resists the TA's lateral rotation - it's simply a bad performing tonearm. I've had it refurbished with new V-blocks and rewired with NOS Ortofon litz and had the dental floss / epoxy fix for the tension wire related sagging CW. It looked like this when I was done with it:
You'd figure I'd be happy with it but I'd rather have a new bung hole drilled in me than do it again b/c after all that work it still proved to be a turd. It was killing the sound of my Stan 681eee, 881S, my O'fon FF15 and VMS20 and it made the Shure's M75/M91/M95/M97 lows smear all over the place and the highs sibilant. On the bright side... It makes the DL-103 sing, which kinda makes up for the sheer ugliness of that spatula for a tonearm - but that's about it.
I ended up doing the only thing I could still do:
yeah, the Ortofon AS-212 was a near drop-in replacement (with the aid of an
adjustment adapter collar base) and it finally cured the impression left by that horrible Lenco tonearm.
