FFYX 10th Anniversary Special Edition Redwood Air Flotation Turntable The Review

After watching the initial thread on the FFYX, I'm glad to see these positive first impressions. Congrats ScaleAutoArt !!
 
Weak point so far is the motor...I think it could be more robust, however it does it's job. And there is a slight ground hum that I haven't figured out yet. And it includes the ever annoying touch the arm hum. It could be my set up with all of those freak-en wires all over the the place!

Thank you sharing your impressions. As a fellow enthusiast for air bearing playback systems, I'm amazed how things have progressed in this area. Congratulations and looking forward to your more considered owner reports.
 
Peter,

What of about most all of our's favorite pre-play cleaning ritual, the carbon fiber brushing? Does the motor have the torque? Is there any perceptible upset of the platter? Is there a landing or centering bearing that keeps the Delrin off of the machined aluminum 'hub'?

I'm so impressed the air system is so quiet, both the source as well as the air and platter. The quietness and your cleaning speak to very close tolerances and low air velocity / requirements. Excellent really. I've given much thought over the years to the air supply side a DIY AB arm and figured that using a "Q" size nitrogen bottle and precision regulator might be the easier route. Again really well done.

No upset. The inertia from the mass of the platter alone is enough. Yes...there is a centering bearing. I will post some pictures this week.
 
Looking forward to some more listening reviews. How goes it with the ground hum issues? Tracking down those can be a pain for sure.

Today I brought in my rpm gauge and set the speed more accurately. Holding absolutely steady at 34 rpm ( my preferred speed). Spin down time from that speed with belt off is just under 3 minutes :banana:

Good stuff. It sounds like you have a winner on your hands.
 
Couldn't tell from the pictures, but is there a ground wire?

The motor is definitely the weak point. Its borderline acceptable but an upgrade would be preferred. He does offer a better motor package and I will talk to him after their new year. It is also imperative that the bearing surface is kept perfectly clean.
 
I was way off yesterday with my spin down time. From 33.4 rpm using my stop watch came to a dead halt after 12 minutes and 30 seconds.

The reason I timed it again is due to the speed variation I am getting from this motor. It has a 9 volt wall wart and I think it may be attributed to the line voltage at my workshop. It tends to occur more during the middle of the day. Late afternoon it levels out.

Any theories?

Maybe it needs a better PS of some sort?
 
Rather than batteries I'd be looking into a heavily regulated PS, to make sure the voltage stays stable no matter what. If the variation in line level voltage (unless it's very excessive) causes changes in motor speed, the supplied PS isn't really doing it's job. Though if it comes with a simple wall wart, is the actual regulation and PS-duty done on the motor unit internally? Does the wall wart put out AC or DC?

Too bad if the motor is skimpy, but on the other hand if everything else is well, then at that price you can spend quite a lot of cash on a better powersupply or even a different motor and still come out rather well.
 
Its a DC supply. The motor has adjustable speed control knob with some sort of scale.

I totally agree... a step up in the motor or supply would be well worth it. I am thinking of testing my Well Tempered motor and see what happens as far as speed stability. It could be the belt as well. Maybe try some monofilament.
