Heh heh, we'll have to be careful or we might have a case of convergence happening here.

I've been thinking too, and came to the conclusion I should be looking for a new modern cartridge with a bright clear future, not an old cartridge with an unknown past! $75 sounds very reasonable (even with an allowance for postage to Australia). And think of the savings I've made over the years hanging on to (and putting up with) this old 681. Surely that can be used as an argument (even to my harshest critic, me!) that I could even go a little further? What would you do if Great Aunt Martha left you another $50 or so in her will?

(A legitimate response is buy the OM10 AND a bottle of Jameson's to enjoy it with....)

Beautiful balance and fullness. This is what I was hoping for with the Empire. So will the Empire beat the 681? I think maybe yes, but if you are buying one, the cost of the more modern, lighter, way better performing, OM10 is only a small amount more. There are lots of vendors on the web that have new OM10s at around the $75 mark. And you can upgrade the OM body by buying only the appropriate stylus. For me, this is one that jumps out and screams BUY ME.

I will be getting a new OM10 stylus soon and should find it tracking at low VTF. The old one is doing great at a bit less than 2 grams. Not having any problem with skips yet. Drags the lightweight carriage with no trouble. So will need to check that with further use.

Hello all linear tracking friends. Seems like a few months have passed with no action on the LT front. The ortofon OM stylus (generic replacement) arrived a week ago and I've been enjoying my LT and TT enormously since. Prior to that I did some construction on the LT arm to bring it closer to finished. The attached pic will give a good idea of the final thing. As you can see it it pretty much based on the general configuration of the real OPUS CANTUS arm but quite different in realization. First off there is the glass V track. For the arm wand(s) I used CROSS Biro refills, cleaned out of ink residue. The carriage members are scrap hardwood and the bearings are still the ceramic hybrid ones from way back when we were fooling around with bearings. The pic shows the current state of the LT arm. I made the base from scrap of the Corian used for the TT, so it matches well. The main mounting block is more scrap hardwood. The vertical post is aluminum drilled for a hardened steel rod which extends up into the hardwood block. A grub screw in the aluminum post locks the height setting, Not wanting to drill holes in the plinth yet and not knowing just where to put them I mounted a neodymium magnet in the Corian disk flush with its bottom face. Then I super glued a utility knife blade to the plinth in the general vicinity of where it should go. Made four tapped holes in the Corian disk and sharpened points on four stainless steel screws placed orthogonally. This provided whatever leveling might be needed. The magnet has sufficient strength to grab the thin steel knife blade even with the small air gap required to fine adjust the leveling of the glass track. The sharpened screws just bite ito the plinth and keep everithing lined up and stable. Should also do whatever the ubiquitous spikes do for energy draining and/or isolation. So there it is. Not quite gussied up enough, but presentable and functional to a very high degree. Tracking is great, sound is beautiful. It's a great pleasure to have the quality of reproduction be unchanged over the whole record. The highs sparkle, the lows are solid well matched to the rest of the sound and the mids are rich and full with no obvious distortion. Not a very scientific description, but the music sings. Found in a bunch of records that I was gifted a virtually mint recording of the sound track from "The Sting" featuring music of Scott Joplin. It is a mono recording but so real sounding it really gives one a thrill to sit back and savor every note. Mono has its place in the world. The TT sits on a shelf in a book case/hutch arrangement. The shelf is about 15" above floor level. To comfortably change records or whatever it is necessary to sit on the floor. Reaching across the arm to do anything is tough. This accounts for the unconventional mounting position of the arm forward and on a corner of the plinth. It's easy and safe to change record. Let's have some progress reporting from the rest of you LT fans.
P.S. The platter on the TT is white Corian. I normally have a good, black TT mat on it. Took it off for the pic so the head shell area and cartridge would be visible.

BillG that looks sweet!

I LOVE the corner mounting.

I use the OM10 as well. Its a real cracker for the money. A true all rounder.....albeit on my SL1210......

I promise I will build my arm for the Sony DD very soon. honest

magnet damped unipivot

Assuming the link opens, you can see I've been seduced by the "other side," and I'm still working on that design, although planning for a major house remodel pretty much means everything else gets put aside, soon.

Bill, I really like the way your LT has evolved and I'm very pleased to hear it sounds good, too. Simple, elegant, just the way it should be. I never would have thought of putting an LT in that corner, but what a good idea. The whole package goes together well.

I practiced glass cutting so when it comes time to do a finished version of my LT support, I'll be able do the glass V.

Later,

Default tangential tonearm

Hello, I write from Spain, I would like tangential arm ...
Distortion is "0" on the test disc newns hifi, but always above 2 grams of force of the capsule.
Can we make a perfect groove track below 2 grams tracking force?
You can see more of my arms artisanal youtube channel.

Welcome to "the other side". Well the unipivot side anyway. I'll do you one better though: the 219 does not have or need dampning at all, and it is a unipivot. I like the delicacy of the sound (w/Grado Sig8 MCZ), and feel if I change anything it might harm the sound.

If I get up enough courage, I'd be willing to try a mag damped system on a 219 variant. My biggest issue would be creating an adjustable gap that my pivot would go through, and then sourcing good magnets in a ring shape.

I'd still like to build a LT, although I think it should use a knife edge as a vertical bearing, at or slightly below the arm shaft, and a roller carriage as used on the Cantus for lateral movement.

A lot of us have the Technics SL1200mk2 turntable. Some say replace the arm
with a better one. Can you use the Cantus tonearm on the Technics turntable?
