Just purchased a vintage Dual 510 with a Shure VST V cartridge.Looks and sounds great and was wondering what newer table and cartridge would be  equivalent plus any opinions good or bad about about the Dual Shure setup?Thanks.

Congrats on your new purchase.

Equivalent in what terms? Your Dual is typical of semi-auto belt driven TT’s made in the mid/late 70’s by a variety of manufacturers. There are very few modern semi-autos being made today. So in terms of convenience and features, it has no modern equivalents.

Now if your talking sound quality, that’s another story and this will launch into the classic vintage vs. modern debate. I have both so I won’t take sides. But I will say that a vintage will only sound as good as a new TT providing it is full functioning and operating at factory spec. So if your Shure cartridge still has the original stylus, then any modern deck with a new stylus will blow it away.

If you do not know the history of your stylus, strongly suggest you replace it immediately. A diamond pushing 40 years old is not doing your records any good. And will affect the sound quality!

The cartridge tracks well and the gentleman said he has not used the table for many years so for a little as I paid I wasn't challenging his integrity. 

Sounds like its an original and no need to question anyone's integrity.  The fact is its pushing 40 years old and regardless of how it tracks, the stylus has been worn down.  Plus the suspension wears.  Its not doing your records any favor.

I have bought, repaired and resold dozens of vintage TT's and the stylus is the first thing I replace.  I suggest you do the same - there are many aftermarket styli for your Shure.  But its your records.

Thanks for the advice.
Took it to the gentleman who does my repairs and said most stylus last 2,000 hours depending in the setup.The Shure still had at least 1,000 left he told me which is good cause I only sit for a couples of hours twice a week.Gives me plenty of to time to sit on my butt and listen to music.
More like 600-1000 hours tops.  But like I said in my last post, they're your records brother.  Good luck.
Well my technician has been in business for 40 years and has done a great job on some of my repairs. Think I'd take his word over yours.Why would he lie,he could say the stylus was all to hell and get me to purchase one from him and make a few bucks!Is that the road you'd take?

You obviously don’t believe me John so why don’t you post this question as a separate thread in this forum and even on other websites. I am sure the majority of lifelong users of vinyl like will say stylus life will be 600-1000 hours depending on care and the quality of records that were played.

I don’t think your technician is lying - he is just giving you bad advice. A stylus is cheap insurance as it is the only thing that is really in contact with your records. But again, they are your records and not mine.

And I don’t go to technicians. I repair my own vintage stuff.

The longevity and wear of a stylus depends on a number of factors. First the stylus profile, followed by set up and and cleaning and finally on the condition of the records.

600 to 1000 is about right. Although a conical will go sooner and super fancy profiles lasting longer. 

My Denon of the past, 160 and 301 were around 500 to 600. My Empire conical about 300. My factory Benz glider around 1200. My soundsmith Benz Glider around 1500 or more. My Benz m.9, with after market cantilever and stylus....well,  I'll have to see but I'm hoping 2000.

Your Shure should be around 500 plus or minus a few. 

Regardless of the opinion difference, if the suspension is good and the stylus sharp.....enjoy it. But when you start to hear inner groove distortion that you can not adjust for it is usually a good indicator that the stylus is going. Meanwhile, keep your eyes open for a great deal on a cartridge with less than 100 hours. Often these come up and you can get a good deal on one. Just make sure it is a good match for your arm and phono section.

It has played very well,and the Gentleman that sold it to me was moving and asking only $35 so I couldn't pass and figured it was worth the risk.
Absolutely and nice score.

The thing about stylus wear is that it is in the ear of the beholder.  In other words, styli don't suddenly fail in any obvious way.  Instead, the sound gradually deteriorates until a problem becomes obvious to the regular listener.  When that happens will depend upon the acuity of the listener and the quality of the rest of the system.  So, in one system a stylus may "last" 500 hours; this only means that at 500 hours a problem became perceptible. In another system with a different owner, that very same stylus in that very same cartridge playing the very same LPs may have lasted 1000 hours.
Thanks for the information. Hope that I can get many hours of enjoyable music from the cartridge. 
I just refurbished my 40 year old Yamaha YP-B4 and replaced the Stanton 680EE stylus with a new elliptical version from Japan, huge difference highly recommended
A replacement stylus for my particular cartridge would expensive as well.
How do u tell when ur stilys starts to go bad
Don't know if this question is directed toward me but when I start hearing distortion is when I need to examine the stylus and possibly change it.

Yes, distortion but I have also found that excessive crackle start to develop in one channel or the other on records that were once free of noise. This is usually a telltale sign that its time to replace.

Something from my wife's dayjob must have robbed-on to me, I find thus thread weirdly interesting: would the opinion of your trusted technician be swayed by suggestions from anonymous "audiophiles" like myself? I do not see myself asking for marital tips frim the strangers... $30 and even a new stylus is tooo pricey?!! Come on, just invite your friends for a listen and if TT sounds better then your CD player then u r set!!!  ;-)
Well my CD players sound pretty nice too!
This is just my personal experience: when TT starts sounding Way better than CDs its time to stop thinking about cartridge/tonearm upgrades. 
I'm  happy with the sound from both.
