Hi Wellington and fellow Micro-Seiki fans,I will have to agree with your findings about the CU-180 as well. I have tried a stainless steel mat with similar results.I own two RX-5000's and cant't stress enough the rebuilding of the power supply with n...

[quote user="jam"] (maybe another RX-5000 as a
flywheel might work?) If not set up correctly(which can be a pain) it can cause
problems. [/quote]
In my case use the RX-5000 as a flywheel did not work. I
mean it “worked” well from mechanical per...

Certainly it took Technics a while to sort out the motor control systems in their serious DD machines. The earlier SP10 Mk1 is not a good example. On the Mk2 they seem to have got it right. Even with that there are other issues like the mat & pli...

I've had an RX-5000 for a few months now. I've read yours and other comments with great interest. I'm a long time high end dealer who is losing his vision and is mostly retired. I've known this particular turntable for about 35 years since it belo...

I would agree that the RX-5000 has some advantage to the SX-8000 and I put the differences down to mainly the air bearing and construction of the platter which will cause softness and a lack of focus (some people may like this). To understand the u...

Hi Romy,
In 1990 the heater on one of my cars blew up (a VW). The rug was soaked with antifreeze and the dealer did not care, so I pulled out the rug and took it to the local laundromat for cleaning. Under the rug, the car had 4 clear, heavy and fle...

Yoshi,What material do you have as damping material in the box and how close is it to the Lowther? These things are incredibly transparent to what is behind them. Some things to consider.If the damping material is within 3 inches of the cone, it will...

Here's my latest hallucination :So I'm sitting there listening and sucking down a beer, when, à propos de rien, it comes to me; more on how to neutralize a suspended floor. After shoring it up with screw jacks (which btw, would make excellent scratch...

I have ongoing project going for a while. I guy in Europe built for me 18-cell 183Hz horn for S3 driver. It is not that I am a huge Multicell fan, quite opposite but for sun 1.000Hz channel I think it might work. In addition I wanted to have Exponent...

[quote user="Lbjefferies7"] I do have an interest turntables now as I am looking to upgrade my sources (digital too). It is doubtful that I will go in such an insane direction...It would probably be much more valuable to dredge up an old RX-5000 or 8...

[quote user="Romy the Cat"]What however is very practicable is some kind of sealed TT mat of 2-3 cm tall, fully filed with mercury. It would be 10kG of inertial mass – it might work… The question is how?[/quote]Ah, this is a GOOD idea! Wood would be ...

Romy, there will be an inner cage for electronics inside the TT stand:This is a sand+shot filled steel frame topped with the same vulcanic slate as the TT stand.I tried to put the cage a la RixRax but it did not work(the picture&explanations are ...

Interesting, in my amp the whiteness of the 6C33C sockets never bothered me. I think if it bother you then you might located the socket slightly below the top panel, this way you will not see them so easer. If you use ceramic base then ceramic is pai...

Thanks a lot Romy for your useful advices mixed with delicious and sometimes spicy
humor which make the meals more tasty ;-)

Measet,As you may know, 316L is a low-carbon austenitic stainless steel which has superior corrosion as well as machining and welding properties. It is generally non-magnetic in the raw state, but cold working can convert tiny amounts of its austenit...

Romy,
I wouldn't assume the ring material in the tube dampers to be sonically irrelevant. Polymer materials are viscoelastic, so should contribute to the damping effect, while a spring-like metal ring would have a more resonant behavior. In any ca...

Retrofunk,Interesting observations. With regard to the speed variations with the flywheel, I have to wonder about your motor. I don't recognize particular unit. Do you have the original RY-5500 motor that came with the RX-5000? The RY-5500 has a buil...

The Manufacturer told me, the Model 3 has a lot of identical parts from Model 1 (Motor-management, Materials, Vacuum, Air bearing, Glass platter...) and they want to serve more customers, Price is 50% of Airforce Two.One of my friends owns the Airfor...

I'm not convinced a constant side load on bearing is good. It causes assymetrical wear. Just seems to me a center balanced bearing with no lateral loads would be better. Merely an intuitive hunch.
As for the copper, yes, it...

Thanks for detailed answer. I'll go for 316L. So I would not worry about magnet issue, especially because also I use CU-180 or Audio Technica AT-666EX mat (air suction type).
As my taste is closer to steel I have plan to make also the 316L version...

In a way you can write some positive / negative about nearly every Design out there. The Micro 5000 & 8000 are 20 years old, they have 2 weak features- a Platter which rings- no suspensionBUT, when we look at their latest units, we can see that M...

The Ultimate turntable only needs to provide for one arm. The ultimate arm. Why compromise its performance with various inferior arm designs.
I'm not sure that high mass is necessarily a good thing. Yes it stores a large amount of kinetic ener...

I have one of my newest Micro Seiki RX-5000 sitting in basement for years and doing nothing and I decided to let it go. I was keeping it for year as some kind of back up TT, in case my 8000 got broken or as TT that I would be able to use at...
