How do you tell your Cartridge needs replacing?
The OP owns a Sumiko cartridge, not an AT. So unless Sumiko offers a similar service to AT, the OP is best off procuring the services of an independent repair shop like the ones you, and several others before you, named.  
I am enjoying my analog system, but what can I do to improve?
Pindac, I apologize if I sounded harsh in my last post. Anyone can say anything about how any two components sound in a side by side comparison, and your report is one example. There’s no right or wrong conclusion in that context. I just disagree ... 
Linear Power Supply?
The LPS perhaps keeps the platter spinning a bit longer because its capacitors hold charge for several seconds after unplugging the unit. Until the DC voltage falls below a certain threshold, the platter will keep spinning. No magic.  
How do you tell your Cartridge needs replacing?
Not many of us have the skills and experience to determine by inspection the condition of a stylus except in the most severe cases of wear, even with a microscope designed to do the job. I include myself as lacking such skills, and I do own a suit...

Pindac, What you reported is "hearsay" evidence, you reported that someone else reported that he or she preferred his or her modified SP10 Mk2 over the SP10R. Here’s another opinion: I find it hard to believe that any SP10 Mk2, no matter how modif... 
Linear Power Supply?
I'm sorry.  Where did I "deny" anything?  I simply pointed out that the OP is concerned about replacing a wall wart that contains an entire power supply, which launched a discussion of switching power supplies (SMPS) vs "linear" power supplies (LP... 
Linear Power Supply?
Viggen, Sounds like in your case the wall wart WAS a transformer, only. That’s different from the situation under discussion where the wall wart is a complete power supply, meaning a transformer plus the downstream parts required to generate DC at... 
Linear Power Supply?
I am not knowledgeable enough to concoct an explanation for why a tube based motor controller might outperform a solid state one, for performing the function required in the Brinkmann system.  But I do know that such a rationale exists somewhere, ... 
Linear Power Supply?
Like I said, it's a matter of individual perception.  Is there likely to be a measurable  advantage to the LPS vs the existing SMPS, in terms of noise in the audio signal or speed control accuracy?  No, I don't think so. But will you hear a differ... 
Linear Power Supply?
You have asked a very complex question, believe it or not. First, one can argue whether "noise" from a turntable motor power supply can even enter the signal pathway. The answer is it can enter by direct radiation of EMI and/or RFI from the PS its...

If you are happier with the Benchmark, so be it.  Good news, in fact.  
I am enjoying my analog system, but what can I do to improve?
Although I am not as vehemently opposed to the L7000 as is Raul, I agree with him in general that you ought to work with what you have, first.  If you can borrow another linestage, either tube or SS, that uses another method of output coupling, yo... 
I am enjoying my analog system, but what can I do to improve?
qwin, After your last one or two posts, I am no longer certain what is your position. The SP10 Mk3 is simply in another league from either the SL1200 Mk2 or the 1200G series, BUT, as Raul already mentioned, no Technics turntable used a coreless mo...

In addition to following the instructions given you by Dover and frogman, you would be well advised to purchase any one of the many digital VTF gauges  that are now available online. There is no need to spend a lot of money on one, but choose any ... 
I am enjoying my analog system, but what can I do to improve?
qwin, I cannot comment on differences in sound quality between an SL1200 Mk2 and the 1200G series, but do bear in mind that there are several variants of the G series, to include the G, GR, GAE, and lord knows what else, and that the low end of th...
