Early SOTA vs New Something: Conundrum


Hiya,

In a nutshell: 

I have a Series I SOTA Star from prior to 1986. I've had it about 12 years. It has early AudioQuest B300 cartridge.  The Sumiko MDC-800 Arm is the best part of the unit. No modifications. No maintenance ever as far as I know.

The Arm was installed where a previous arm sat (not by me) and is not positioned correctly. 

It needs at least a new cartridge. But after a chat on the phone with SOTA, it sounds like after these years (plus the arm mis-location)  it needs a bit more than that. Upgrades, adjustments etc...

I could do a new cartridge, but it appears a waste without doing other needed work to the TT.

Cartridge, Tonearm board with other needed upgrades I'm looking at about the price of a new table. Such as a Technics 1200G or some such version of.

Time to jump ship? Or I could ignore it all and continue to run it as is. It honestly doesn't sound horrible. Not great either. But bad enough I don't play vinyl much anymore in favor of CD- digital

I do have an extensive LP collection and wouldn't mind listening to it...

Cheers,

RW

An update:

The new SOTA belt came in.

I know I had replaced it once before years ago, but this one is quite different. Much narrower in width and quite a bit shorter. Whatever; it works very well. The old belt took a number of seconds to reach speed- due to slippage I am sure. The new one pops right up to speed in about two seconds or so.

The new AT ART9xi cartridge has been installed. Incredible improvement there as well.  I had installed a new stylus into the AQ B200 a few years ago, but this new AT cartridge is lightyears ahead in all respects. Considering it will improve over a number of hours still, I am quite shocked with the superior sound quality right out of the box.

 

All I can say is this gives a much better sound for what Analog is known for- and I had allowed to slip away all these years...

Hi RW.  If you are going to use the Star in any capacity, you need to get an armboard cut specifically for the geometry of the Arm.  Otherwise you will never be able to align the cartridge correctly.  You can get a SOTA cut armboard and the composite armboard is worth the money or you can locate an aftermarket blank or make your own.  Regardless you will want to precisely determine where to drill the tonearm pillar hole for the correct alignment.  Have a machine shop to the drilling.  That Arm is still worthy after all these years.

I owned SOTA's, gen I-III, Stars and non-Stars going back to the early 80s and have done most of the maintenance the last 20 years.  Inspecting the bearing thrust plate, it's imbedded in the base of the spindle, and the bearing itself are the first things to do.  Cheap, easy and very important.  If the thrust plate is damaged and many are, you will need to ship the entire platter/bearing assembly to SOTA for inspection and repair.  If you are handy or have a machine shop, you can replace the synthetic sapphire with delrin rod for cheap.   The spring replacement kit is cheap, easy to do at home and important for stability, speed and tonearm performance.  This is just the start so you can either go the upgrade path, buy a new one or seek alternative turntables.  The Technics 1200 series offers good performance and excellent value.  It can also be modded.  Regardless, do the armboard in the interim.

Here ya go!!

1982: AudioQuest Phono Cartridges AudioQuest begins selling phono cartridges and achieves almost instant success with the AQ-404 moving coil cartridge. The AQ analog tradition continues to this day!

@rwbadley just curious, I'm assuming your 30 yo SOTA uses an ac motor. Does the new current SOTA use a DC motor? Only reason for asking is that I find tables in general that use a DC motor have better PACE.

Thanks for all your replies

I don’t know if the motor is ac or dc. I suspect dc but could be wrong. 

Thanks for the tip on the arm board. I might go that route and the bearing service, but found when the new cartridge (AT art9xi) went in it mostly solved the issue with proper alignment. I think the AQ200 was not able to get far enough forward but the AT is shaped differently, so I’m happy with that. 
 

As for the bearing, I’ll leave it be for the moment as the platter spins smooth and I am getting no noise from playback. Plus another issue just popped up
 

A day after the cartridge install the new problem arose. Of the two buttons that turn the motor on one has seemingly failed as I now had to install a power strip with shutoff switch to turn the platter off. Both buttons down is 33. Both buttons up used to turn it off but now it goes to 45 rpm. So no way to turn platter off without the power strip switch. Oh well, it’s always something…
