Holmz Posted March 16, 2022 Share Posted March 16, 2022 I have been eyeing off dual armed TTs. Mostly because the new phonostage has two inputs. Are they worthwhile? Or a bit of waste of time? And just have one good one? One limitation of the SOTA is that I am limited by tonearm length. But I am not 100% sure that a longer arm is better other than in “geometry theory”. Question #2: Where does one get the flexible wire that is used for the tonearm anti-skate weight? (I have a broken wire and with luck I might find the weight in the chaos of the moving.) In the mean time the weight from Singapore went on walkabout so I ordered a Project one to get me by. Link to comment Share on other sites More sharing options...
Richard Vandersteen Posted March 17, 2022 Share Posted March 17, 2022 I use 2 arms, one stereo and one mono, sometimes I mount a mellow warm cartridge for so, so recordings. My TriPlanar uses fishing line for the anti-skate. RV 2 Link to comment Share on other sites More sharing options...
Holmz Posted March 17, 2022 Author Share Posted March 17, 2022 Thanks RV. I was a bit uneasy getting the new phono stage… now I know why. I am looking a new pre amp and… a TT upgrade I’ll order the fishing line. Ta Link to comment Share on other sites More sharing options...
TomicTime Posted March 17, 2022 Share Posted March 17, 2022 i don’t have many mono recordings, the Triplaner is enough for me. Your SOTA is limited to about a 9” arm and without some modifications will not accommodate the Triplaner ( VTA tower and base dont fit in the plinth / arm board well ). Having said that arm length is a tradeoff between a few other important variables besides slightly lower error…increased mass isn’t free nor is a stiffer / low resonance structure. I have yet to hear a longer arm bowl me over….but who knows, i certainly haven’t heard them all…. Link to comment Share on other sites More sharing options...
TomicTime Posted March 17, 2022 Share Posted March 17, 2022 i think w Eclipse motore and speed control for your SOTA you would be hard pressed to do better w another TT for under $10 k… my buck fifty…. 1 Link to comment Share on other sites More sharing options...

Thanks Jim. Damn that new phono stage! It having the two inputs has me thinking… I was looking at a Denon DP-80 and a homemade plinth. And also something like an old Luxman PD-444 or PD-555. I put the new belt on the SOTA… but it is still throwing the belt sometimes. If I do not pre-spin the platter the belt get thrown. (There is a reason I made knurled knob for the screws that hold on the switch cover.) The other thought I have been having was to remove the guts of the Sota and put it into a new base/undercarriage, so that I have more area. As you mentioned I cannot even use a Triplanner arm. So it is a case of steel, give away, modify or keep the Sota. or Go with a new TT deck. @TomicTime if you talk me off the ledge, I’ll give you two buck and a fifty cent CD.

Stringreen Posted March 19, 2022 Share Posted March 19, 2022 (edited) I know skating does exist, however in my system I prefer none.

Holmz Posted March 19, 2022 Author Share Posted March 19, 2022 Well at the moment the style rips across the record towards the label without it, so it needs more than zero. Most do alter the amount as the arm moves… But maybe some f the problem is in the arm. I probably need to order a USB microscope to look at the stylus.

On a properly designed arm the anti force varies across the record. I find this ends up with about half the recommended amount. RV 3 Link to comment Share on other sites More sharing options...
bkeske Posted March 19, 2022 Share Posted March 19, 2022 Great idea Richard, will have to try that. I utilize a blank LP method (have one just for this purpose), and adjust so the arm barely and very slowly moves towards the spindle, per Peter Lederman’s recommendation. But always open to various ideas. 1 Link to comment Share on other sites More sharing options...
Moose Posted March 19, 2022 Share Posted March 19, 2022 I have a Dr. Feickert Firebird with 2 tonearms: a Kuzma 4PT 11" arm, and a Graham Phantom III 10" arm which was on another turntable . My plan was to put a mono cartridge on the Graham, but I haven't done it yet. I have mono records, but they might amount to 1/10th of my record playing, or less. I'm thinking of looking for another turntable to put the Graham on and using it in a different system. It (and the Kuzma) has interchangeable wands which would facilitate a cartridge swap, but the remaining parameters, VTF, VTA, azimuth, anti-skating would still need to be tweaked, so it's not as quick as a dedicated mono arm. A turntable that accepts 2 arms has a pretty big footprint. It's also a pain to reach the second arm. I guess I'm saying don't let a second phono input push you toward 2 arms. Make sure you really want them. If I played more mono records, it would definitely make sense. 2 Link to comment Share on other sites More sharing options...

(I have no idea on the shipping cost, but my buddy said his had a long gestation period before the rebirth. I think it is over a year.) I put in a bid on a MicroSeiki DQX-1000 yesterday, but that was declined. But it looked pretty easy to chuck and arm onto. Right now the TT feels like a starfish awaiting growing just a single arm.

Holmz Posted March 20, 2022 Author Share Posted March 20, 2022 The starfish lives! It did not require a microscope to see that the old stylus boom on the ‘blue point special” looked like a grasshopper leg after a bird strike. A bit of a quick-n-dirty set up on the Garrott bros p77i… Visually it looked about right, but the overhang was difficult to determine with any confidence. Then I had to download an iPhone RPM app, in order to get a strobe from the phone to adjust the speed. Generally it had less sibilant sounds than I have had in the past. I an not sure what a micro scanner II stylus is? (Maybe a sort of line contact or Shibata?) Anyhow I generally liked what I was hearing. And it was a huge improvement to what I recall (distantly) what the Sumiko “Blue Point Special” was doing. It would be interesting to understand what an upgrade fron this would be, and what it would sound like. Then I played some LPs and took some notes: Paul Desmond Trio - (Very nice) Ricky Lee Jones - (This great) Lena Lovich - New Toy (A bit bass light) Tool - Fear Innoculum (I am not a great fan of Tool, but my neighbour/mate loves it.) Human League - Dare (which needs a clean, and it’s pretty center focussed) Kate bush - Inside kick (which looks like it is an LP from Japan… some sibilant sound on it) Violent Femmes - Violent Femmes (They must have be the consistently poorest US recordings made, and on 180 gr vinyl no less.) Belafonte - Midnight Special (which is good.) They Might be Giants - Flood (very good right from the start.) The Cars - The Cars (This had a surprisingly wider spread than I recalled… Probably because when I listened to it in the past I was distracted with company in my youth.) Jefferson Starship - Spitfire (Sounds good, but not too much my style.) Talk Talk - The party is over (which seems like a lot of UK new wave had the lead singer standing back… or reverbed??) The Clash - Combat Rock (this is good too.) Wide Boy Awake (which is deeply UK 80s new wave) Doug MacLeod - Come to find (Wow this is really good, and out is always a go to.) Otis Redding - Dock of the Bay (mono -180gr. And it is pretty stunning, the whistling was clear and sweet.) Makoto Terashita Trio - some album name is in Japanese (180gr - I have no idea where/when I got this, but it has a wide stage and is Jazz/lounge oriented - very nice and well recorded.) Van Halen (only God him/her self only knows when I got this 180 gr LP - but it sounded pretty good on the song “You’re no good”.) The Special AKA - In the Studio (A nice album from late 80s - Nelson Mandela was freed, and the wall came down, about a week after eldest daughter daughter was born.) Spandau Ballet - Through the Barricades (Right from the intro of track 1… wow… this is stunning.) Super Tramp - Crime of the Century (Started out OK, but a lot of hard panned sounds, which distract me… but good in general.) Springsteen - Born to Run (This has been played to death over the years but maybe the micro scanner stylus reaches deeper into the groove? The opening track always sounds like the platter’s pitch of off… CD always sounds that way too) Watchman - movie soundtrack (I was not expecting it to be like Vangalis, but it was nice.) Picture is with the colour vinyl Tool LP, and that new Korf headshell. The belt did not fall off, so I may put the motor cover back on. Link to comment Share on other sites More sharing options...

Steve Edwards Posted March 21, 2022 Share Posted March 21, 2022 There is also this one; a few bucks less. Brian, the directions suggest lowering the arm onto the center of the record and adjust skate until the arm remains stationary in that spot. You like to adjust so the arm barely and very slowly moves towards the spindle, per Peter Lederman’s recommendation. It sounds like you're pleased with the results, but that leaves me wondering about RV's comment: On a properly designed arm the anti force varies across the record.

Nor if the stylus riding on the nose on a d a smooth blank disk, would be the same as in a track on the walls. I it should be I think, but in the end it seems like a “close enough”. I don’t know if I have the fine tuning ears for it… but maybe I do, as the SPL is slightly higher on the LHS speaker. I’ll need to figure out whether it is the pre-amp, tube amp, or speaker or room… I’ll start with swapping the speakers first. I have REW on an Intel NUC, a UMIK, and time… so I have few real excuses. (I’ll do this in the digital domain for the source.) But is there a pink noise LP? I found a place that cuts LPs, so maybe I’ll enquire as to the cost.

Peter’s technique is actually a Frank Schroder technique, which Peter happens to support.

I’m intrigued by this idea, but have not tried it yet, in addition, to really fine tune in this way, I would think it may require two people, one listening, one adjusting the AS.

The mono Beatles releases are entirely different performances, and they're just as great. Pet Sounds is in mono. Hurdy Gurdy Man in mono, ... It does sound good played with the stereo cartridge. If you have a mono button, that helps, too. A mono record groove isn't modulated the way a stereo record groove is, so you can reduce noise even further with a mono cartridge.

If you have a clamp (or are wiling to affix it to the platter, perhaps using tape) a CD-R works great. 1 Link to comment Share on other sites More sharing options...
