OK-- so some time ago I asked for some advice on a new, inexpensive TT. The advice came back: Thorens TD-160, which I bought and I liked very much! Much better than my Music Hall MMF 2.1. Until....
Disaster 1:
It played a little fast, so I thought maybe the belt was bad or wrong. Got a new belt and it played EVEN FASTER. Asked on DIYAudio and response was: wrong spindle on motor.
Cost to get a new spindle: Between $30 used on Ebay (if you can find them) or $100 from a specialty shop.
Reaction: Yikes.
So, I thought I'd play with it anyway for a while. Then it started skipping when it got close to the center of the record. Thought maybe the anti-skate was bad and messed with that for a while. Then...
Disaster 2:
The anti-skate tension line / tonearm wire snapped. So did Kofi.
Reaction: Rrrrr... arrghhh... Blblblblblblblblblblbl!!!!!!!!!!!!!!
OK, OK, no big deal. Just need to rewire the whole thing as recommended by audio-kraut (that's his avatar name, folks) and get a new pulley or a new motor or, as recommended by Carondimonio, take the sander to the original pulley.
Reaction: Pop! Fizzzzzz..... <gurgle, gurgle, gurgle...>, (repeat until drunk).
So, here's the deal. Running low on patience and having built up some serious karma for the holidays, I'm thinking about buying another TD-160 off Ebay. I know, I'm a glutton for punishment. I may be able to bag one for around $125, and use this one for parts. I suspect that the tonearm on this one is shot, since even the removal of the wire did not fix the inner record skipping issue.
And now, the question:
Should I:
(a) stick with this one and try to fix it?
(b) buy a new-to-me TD-160 and use the old one for parts?
(c) buy a linear tracking TT (theres an HK linear on Ebay that looks neat)? OR
(d) make my own music by cupping my hand under my armpit and squeezing?
Please respond by selecting the correct letter and elaborating on the reasons for your choice. All answers will be reviewed by the Secretary General as a possible remedy to his dilemma. The winning response will receive a hearty "hey hey!" and perhaps some knitted mittens from Mrs. Annan.
Yours in frustration and ignorance,
Kofi

Why not just look for a different tone arm for that TT. I don't remember that as a great arm anyway. Try to file down the spindle only if you sure it's to big. Just take your time and do speed checks often. I would let the motor run and use fine sandpaper or a small file, but be careful. Once it's to small, well it's not good.

Chipco,
Allow me to repeat the instructions for the assignment:
Please respond by selecting the correct letter and elaborating on the reasons for your choice.
OK-- sorry I'm being a smartarse.
Yes, it crossed my mind that the Thorens line of turntables have something against me. If I do ultimately receive persuasive assistance that spurs me to buy another TD 160 and THAT one screws me too, then I will purge my Thorens collection in the all-cleansing fire.
I have a parting line all ready in case of this contingency:
"Hey TD 160s! when you get to Hell, tell 'em Kofi sent ya!"

(d) make my own music by cupping my hand under my armpit and squeezing
whats wrong with kraut?
Anyway, since your technical abilities seem rather limited and the job stress seems to get to you, I would recommend D, especially after using deodorant so that concomittand (I like using fancy words, just trying if it fits here) with the sound a rather pleasant odour gets relaesed. Especially recommended before engaging in spousal engagements mafter a romantic dinner.
Seriously - why not consider the td 145 with the tp 16 arm? And it even lifts off the record at the "grooves end" - no, it does not return the arm to the start position.
But I said consider - not "I recommend". I am allergic to economic sanctions...
b - probably most logical
That's what I thought. I really liked the sound of the Thorens, but the, shall we say, "issues" I had with this one made it more of a frustrating endeavor than I would have liked.
d - can I hire you to play at my anniversary?
Doing a Bah Mitzvah in February and I got the D'Appolito wedding in May, otherwise I'm free and clear. Contact my agent.
Kofi Annan should stick to CD's
Sounds like my wife. Hey, you been talkin' to my wife? You stay away from her, or the last thing you hear will be the armpit rendition of "Taps", capish?
your technical abilities seem rather limited
Yep. My think-i-fying abilities ain't so good either. Public education, baby.
I can put together the audio (tube amps, mostly) and do a few things with the turntable (balancing, mounting carts, etc.), but once it got to the level of neutrinos and string theory, I raised the white flag. I think, AK, your last instructions to me were along the lines of:
... now take the electron microscope and set the first condenser lens aperture to Avogadro's Number...
Can I be blamed for trying to find an easier alternative? Don't answer this one.
Oh yeah: Antidisestablishmentarianism!. There. Fancy word and non-sequitur all in one. I may have made that one up, though.
The TP 145 sounds nice. Too nice. In fact, if the arm came up off the record automatically like that, I'd never get my fundament off the furniture.
I think I may try for another TD 160. They're readily available on Ebay and I liked what I heard. Besides, the Karmic balance of the universe simply would not allow for another debacle, right? I think that's string theory... is it string theory? Does Murphy's Law trump string theory?

OK, I'm becoming convinced... I looked on Ebay and so far, no such tonearms available. Other than Ebay, any other sources for these?
f) build a 50 Hz motor controller...
To paraphrase Audio-Kraut, "my technical abilities [are] rather limited". Can I get a push in the right direction here? Can I find out about it at 50Hzmotorcontrollers.com?

Oh, so I'm supposed to do it myself, am I? Like its some kind of hobby? Well... uh... you have a point here.

Right! One thing I won't have anyone saying is that tha K Dogg gave up! I won't give up on Mideast peace, I won't give up on House Resolution 1441 (OK, bad example) and I won't give up on the Thorens TD-160! YYYYAAAGGHHH!!!
That's it! I'm getting a tonearm! I'm building a 50Hz motor controller! And most importantly...
I NEED MORE HELP!!! YYEAAAHHH!!!!
Kofi
Hey-- I just got done looking for tonearms on Audiogon.com (seems like they have lots for sale) and I just had to look at the zillion dollar tonearms they have for sale.
Let me say first that while I would never buy a three-thousand dollar tonearm, nor would I begrudge anyone that has one, doesn't the price / enjoyment ratio graph get a little flat at three grand?
That is, is there and can there be a mind-numbing, jumping-for-joy, karate-kicking-in-the-air difference between a $300 arm and a $3,000 arm?
Just asking. Also, if anyone could lend some guidance on a design for a 50Hz motor controller (if such a thing can be made with limited funds and mental faculties), please let me know.
Also, Rega 250 for $175-- good deal or no?

Reasonable - could use a little upgrading - check with origin live
Kofi Annan said:That is, is there and can there be a mind-numbing, jumping-for-joy, karate-kicking-in-the-air difference between a $300 arm and a $3,000 arm?
Ah, the seemingly ever present myth of declining marginal utility. The whole of history, it seems to me, is a history of declining marginal utility, nothing essentially new under the sun, it's all mostly been done before and, in my dad's estimation, why not drink chokecherry wine?
Is the marginal importance of a difference larger or smaller (a) before one is alive to that difference and (b) after?
Kofi Annan said:Rega 250 for $175-- good deal or no?
Not a barn-burner deal... but fair (i got $230 USD for a new 300 -- but that was when the USD was worth a lot more than it is now -- USD has lost about 30% since then). The RB250 is considered by some to be a better starting place than the RB300 (me included). It is a really good arm... possibly better than the Thorens deserves -- but it can always come off and go into the next TT.
Also, if anyone could lend some guidance on a design for a 50Hz motor controller (if such a thing can be made with limited funds and mental faculties), please let me know.
Basically you are building a device that takes 60 Hz AC in and generates 50 Hz AC for the motor. I have seen it touched on in a couple threads, but haven't seen anything that would let me go ahead and build one (i have a Linn bearing, inner platter, & 50 Hz motor that deserves to be used in a project someday)
dave
Kofi Annan said:is there and can there be a mind-numbing, jumping-for-joy, karate-kicking-in-the-air difference between a $300 arm and a $3,000 arm?
yes.
But keep in mind that the TT itself is more critical than the arm (ie i'd put a $300 arm on a $3000 TT, but not the other way round)
dave
present myth of declining marginal utility
when it comes to utility - there is none in a tone arm except for some audio nuts.
It is not the utility what has been asked - it is the audible difference, and there I douby that a 3000$arm is 10 times better than a 300 $ arm. A combination of an RB 250 or 350 with a good shure system - V15VxMR at 500$ is maybe not the perfect system, but will allow me a musical enjoyment that a 5000 $ combo definetely will not - price is a consideration with me.
A tonearm only performs well with the right system - physical parameters see to that, and it is very much tougher to find a system for a very lightweight tonearm than for one like the "middle weight" rega.
I have reviewed the possibility of chnaging the 60Hz to 50Hz and it really looks like a potentially expensive process and a pain in the *** to boot. I am also afraid of sanding / filing down the spindle for obvious reasons.
That said, wouldn't a homebrew DC turntable motor / PSU with analog speed adjustment do the trick? Anyone got any links to a design for these?
Looked on DIYAudio forums, but I have come up empty, so far.
Thanks for all the great advice. If your respective countries ever become unstable, I'll make sure you're at the top of my list for Loya Jirgas.

Thorens 160 Information
Kofi,
Clearly, I would choose "A" simply because you don't want Mrs. Annan ticked off because you now have two turntables (especially one that is collecting dust!). Also, you've "made your bed and are now laying in it" so to speak and you have to redeem yourself somehow... (just buying a new one doesn't qualify IMHO...)
The above having been said, here's more info than you might want but I did this so you and others would have reference links to lots of information on these tables...
I've read that the Thorens is very similar to the Linn LP12 as well as the AR tables. If you can find someone who would be willing to measure the inside platter diameter, perhaps you'd get lucky and just be able to order a pulley from Linn or AR... Or, you could just have one machined out of brass if someone will give you the measurements of the original.
Your other option would be to go with a DC motor system like Teres uses that would take the table to a completely different level...
One other option that I haven't seen mentioned would be to grab a PS Audio P300 powerplant with multiwave. You can step the freq up and down and you could very the speed that way. The other similar option of this type would be a VPI SDS unit or the Origin Live unit...
Based on what I've read, this table looks to be a very good starting point for some serious tweeking...
A couple of other thoughts that I will mention:
Regarding the skipping near the center of the record. Was your tracking force set correctly? Was the table level? Lastly, what is the condition of your stylus? If any of these were off, the table would react as you described near the center of the record...
Also, if memory serves, there was a group buy some time ago on the Maxim motors. I Searched and the thread is listed below; perhaps you might consider sending an email or starting a new thread to find out if anyone has an extra that they'd be willing to sell you...
Here are some related threads that I thought you'd find interesting:

Enjoy and Happy holidays! 🙂
Apogee,
Thanks so much for all the links. I have learned quite a bit over the last few weeks.
The only remaining question I have is: Are you ready for the punch line?
I decided I would take another look at the motor this afternoon to determine if it really was the spindle. When I did, I noticed that the spindle had a dark mark on 1/2 of its circumference, but not on the other half.
Hmmm....
Being an Encyclopedia Brown fan, I decided to investigate further by removing the spindle using the directions on The Analog Dept. website. On the TD-160, there's a brass collar holding the spindle onto the pulley (right terminology?). According to the website "Brass locking collar has two set screws".
When I loosened the first screw, the entire assembly came apart immediately.
Hmmm....
So, the other screw was never tightened. It must have contributed to a crooked mounting, causing a greater distance between the pulley fulcrum and the platter, I thought. Well, actually, first I thought, "now you broke it FOR GOOD, DUMBASS!", then I thought the other thing.
I reassembled the spindle / pulley, only this time making sure to tighten both screws. When I started it up: WALLA WALLA, WASHINGTON! Its holding speed at 33 1/3!
Little Stevie Wonder sounds little... but not too little! And wow, what an improvement over my old Music Hall MMF 2.1!
I really want to thank everyone who helped me through this one. I know I can be a real pain, and a dumbass, and a stooge, and a lazy bum, and it really helps me to maintain those qualities when I have support like this from all of you.
I looked at the Grace tonearm link you sent, thanks. I'll be looking into that one, but I will likely purchase a used RB-250, since they seem to be in great supply and can be tweaked, upgraded, etc.
Thanks to all! Mittens and scarves to all who want them! Get knittin' Mrs. A!

On the TD-160, there's a brass collar holding the spindle onto the pulley (right terminology?). According to the website "Brass locking collar has two set screws".
When I loosened the first screw, the entire assembly came apart immediately.
Hmmm....
So, the other screw was never tightened. It must have contributed to a crooked mounting, causing a greater distance between the pulley fulcrum and the platter, I thought. Well, actually, first I thought, "now you broke it FOR GOOD, DUMBASS!", then I thought the other thing.
I reassembled the spindle / pulley, only this time making sure to tighten both screws. When I started it up: WALLA WALLA, WASHINGTON! Its holding speed at 33 1/3!
Little Stevie Wonder sounds little... but not too little! And wow, what an improvement over my old Music Hall MMF 2.1!
I really want to thank everyone who helped me through this one. I know I can be a real pain, and a dumbass, and a stooge, and a lazy bum, and it really helps me to maintain those qualities when I have support like this from all of you.
I looked at the Grace tonearm link you sent, thanks. I'll be looking into that one, but I will likely purchase a used RB-250, since they seem to be in great supply and can be tweaked, upgraded, etc.
Thanks to all! Mittens and scarves to all who want them! Get knittin' Mrs. A!
