Vintage Technics SL-1000A vs Pro-Ject Debut or Exp


I'm the original owner of a stock Technics SL-1100A, currently with a 25 yr old Shure V15 V-MR cartridge. I'm just dragging it back out after years of storage to revisit my LP collection. It seems to work fine and is in good repair.

I'd be interested in making some reasonable upgrades to this turntable, and would like your thoughts on those, but I'd also like to get a better idea of how good this table really is or can be in comparison/rank with current tables like the Pro-Ject Debut/Expression lines and similarly priced new tables.

Has table technology advanced to the point where I'd be better off buying new, or would I be better off doing some upgrades to the old Technics?

By the way, with the changes I mentioned above, you may not care if a Project is somehow 'better', as this particular Technics has a good, solid bearing for proper dynamic response, and it does have nice pace, rhythm and clarity. One reference for me on this is our Micro Seiki BL-91 heavy belt-drive TT. And I still enjoy the Technics.

Perhaps the ultimate limitation of your TT will be its stock tonearm, but as I never got a chance to use it, I am only speculating. However, I can tell you that a few years after your TT was introduced, large improvements in tonearm design appeared from Audiocraft, Fidelity Research, Grace, Micro Seiki, Mistubishi (on their DP-EC20 TT), Technics, and others.

Thanks so much for the response and your insights. All very good ideas. I'm going to jump into the damping project this weekend.

I'd like to get a custom arc protractor made to see if I can optimize the stock arm - can you recommend any vendors for that?

Also would be interested in upgrading the arm, but don't know where to start for sourcing an arm board. I would think the exactness of the cutout and mounting holes would make or break it. Any ideas on sourcing?

I did contact KAB, and although they're very familiar with other Technics models, he wasn't able to offer much in the way of specific upgrades help on the SL-1100.

Glad to be of help, George.

To create an arc protractor, what matters first are the values for your tonearm's Effective Length (235mm) and Pivot to Spindle distance (221mm) [from Vinyl Engine's Technics page]. While there, perform a search for Arc protractor, or perhaps contact Galibier Turntable company for guidance.

For a making a blank armboard-- the measurements are indeed critical, but easily within the capacity of any decent workshop for wood or acrylic. One has to know the outer dimensions of the plate and the locations of its eight mounting-screw holes. Those you can take from your current board, likely without dismounting it.

And there is the one large hole to drill for your future tonearm. This hole's location is determined by that tonearm's template laying onto your mounted but-still-blank armboard, as it is the pivot-to-spindle distance you are trying to get right.

The Technics model/part number for the blank cast armboard is SH-11P1, and the wood version is SH-11P1W. You would see they each have radial lines pointing to the spindle, for ease of use with the templates of other tonearms. Have a look here: SL-1100 details and here SL-1100. Your machine, sold without tonearm, was called the SL-110.

It seems you should plan on having your own armboard made to use another tonearm, since finding a new blank one will likely take quite some time. But your stock arm is not terrible at all if you change out its headshell. And if you look underneath your existing armboard, you may find the old arm easy to remove without damage, and to open up the existing hole for another arm (if necessary). Someone on EBay-Australia is selling your arm/armboard assembly for AU$100 right now, FYI.

Best regards,

Thanks again for your sage advice. In terms of optimizing the stock Technics EPA-110 tonearm with a new headshell and cartridge, I have a few questions maybe you can help with.

I've adjusted the arm to the specs on the AccuTrak UNIVERSAL PROTRACTOR from Vinyl Engine, and I think it's working pretty well, although limited in low-end extension and depth of soundstage. I'm currently running a 30 year-old Shure V15V-MR cartridge with the stock Technics headshell. The stock headshell with screws weighs approx 10grams and the combo clocks in at approx 17grams. I have not been able to find the Arm Mass specs on the stock EPA-150 arm to determine specific compliance. BTW this stock arm can be adjusted for VTA but not very accurately. Basically it's the "loosen the screws and have the whole arm drop into your hand" type of thing. I've got the arm as level with the platter as I can get it.

Headshell: I'd like to replace the headshell with an adjustable azimuth unit as you suggest. What I can find new comes down to the SUMIKO HS-12 (http://www.needledoctor.com/Sumiko-HS12-Headshell), the LP Gear ZupremeĀ™ (http://www.lpgear.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=LG&Product_Code=LPGZHEAD&Category_Code=HEADSHELLS), or the Rek-O-Kut http://www.garage-a-records.com/products.php?cat=127). All seem to weigh about the same - 12grams. Any thoughts about preference/recommendation on these?

Cartridge: With one of these better but heavier headshells, what are my limitations in types of cartridges? I've always used MM cartridges - should I try an MC? My phono pre will accept both. Can you recommend any cartridges specifically for this setup in the $350 range?

Thanks again for your help-
George

A replacement stylus, Jico or SAS for the Shure would let you know your limit of what you have now. You may not find the tables you mentioned to be that much of an improvement. I went down a similar road. Be careful of going LOMC, matching your cartridge specs. to your stage is paramount.
