.....and I could use some advice please and thank you. There’s a Micro Seiki BL-51 incoming that needs a tonearm. Looking for medium-ish mass and am considering the following arms. If the speed is correct and it sounds good, I might even swap the Jelco 750 from my Thorens TD-160 Super. I’m really leaning hard towards the Yamaha.

I'm thinking an Acos or a Technics might look awfully nice on that turntable.

@Thermionics , funny you should mention this. There is a Rega (Acos) arm for sale on eBay U.K. but I’m betting it will go out of my range very quickly. But there’s always hope.

Technics might be a good option I didn’t consider. Which one, SL-1200/1700 series? Something different?
 
What does the spindle to pivot measure at? I can tell you that I (and a number of other folks on forum) would heartily recommend a Fidelity Research FR-24 MkII if you can track one down. Wonderful and flexible arm, good enough for whatever cart might tickle your fancy. S to P is 230mm on it.

That's exactly the question I was going to ask, and the solution I was going to suggest.

You, sir, must be brilliant!
 
Effective length of 237 mm with an overhang of 15mm. So, that’s 222mm, correct?

There is a FR24 on eBay now but was hoping to spend just a bit less. Maybe I’ll have to reconsider.

Woulda been lovely if it was 210mm for L75....

Great minds and all that. It really is a terrific solution and *psssttt* they ain't getting any cheaper. Blame me, I can take it. I do think that not only are they a wonderful arm, but also represent a decent investment as well.

That good compared to 54 or 64?
 
You could always keep it in the family: the Stax UA series arms are supposedly made by Micro Seiki. ;)

The Grace G840 is also a fine arm.

Many of those tables of that era were 210mm. Let me tell you the solution I went with for my R-O-K B-12H - Nottingham Ace Space arm. Terrific arm and a drop in fit, right down to the size of the hole. Dunno about the hole size in a Lenco, but the S-P is dead on. Shamelessly gratuitous pic:

Nottingham...must be more exxy than the turntable itself lol
Indeed, though I got the table for a song compared to what they go for lately and the arm was a steal. It came in to my local dealer with a Nottingham table, but the new owner had an arm they wanted to mount already and they didn't want it. It hung around orphaned for quite awhile and then I got it - dealer cost I think.
 
Is 54 heavier then? 12” as well?
I believe the 54 and 64 are both the same length as the 24, but different degrees heavier depending on the model. The 66 is the 12" and 14 is similar mass to the 24, but with less complex bearing design. I am convinced that the real glory in the 24 is the incredible bearing quality. It allows the arm to successfully carry carts of much greater mass and energy than one would expect.
