It's rare to find one of these super cool 'tables in working order.

Plus this is the first one we've been able to offer since we started that meets our standards.

Coolness factor is a 10 and ease of use is also a 10. You never have to touch the tonearm as everything is push-button activated.

It's an automatic table meaning it will queue up and detect the end of the record for the ultimate in convenience.

Everything works as it should: speed selector, speed trims, arm movements, and it produces a great sound.

The cartridge was well cared for and shows little to no wear under our microscope. I lubricated all the moving parts to ensure smooth operation and tested the unit thoroughly.

The included and installed phono cartridge is a Moving-Coil MMC4000 example from B&O.

While the turntable is in very good shape with no significant signs of use, the dust cover does have some scratches as to be expected from a piece of this vintage.

The SkyFi Testing Process for Turntables:

First we try to identify any mechanical issues, particularly in the tonearm bearings.  We check for freedom of movement or any resistance on both the horizontal and vertical range.  There is a quick test for this which involves placing the table on its front edge and allowing the arm to swing freely like a pendulum.  We then make any adjustments necessary to achieve minimal resistance and sometimes adjust the bearing pressure.  On gimbal tonearms we inspect the cone tip with a magnifier.  

We then asses the platter speed by using one of several methods, the most accuse is a playing a test tone on a test record and measuring the frequency out put with a frequency counter or oscilloscope.  We also utilize test equipment to measure the wow and flutter to ensure its within spec.  We do this for all speeds available for that particular model.  Adjustments are then made to achieve proper speed which will vary depending on table drive design.  Some require an adjustment of an internal or external potentiometer, some will require a pulley or motor adjustment.  We also inspect the platter bearing to ensure its properly lubricated keeping in mind that some don't require lubrication at all.

We then inspect the power supply and address any issues with overworked capacitors particularly on Linn and later Thorens machines which tend to need attention.  

On fully mechanical vintage tables like the Thorens TD124 and Garrard 301/401 we will go thought the entire mechanism, replace any worn parts and lubricate all components necessary to ensure smooth operation, speed change and low mechanical noise. 

When fitting a new cartridge we will go through our detailed calibration process which can involve as many as 12 steps depending on the arm design.  We perform this work on our custom turntable calibration rig which was developed in-house.

Some of these steps include:

• Pivot to spindle adjustment

• Tracing force

• Anti-skate

• Tonearm height

• Lifter height

• VTA

• Azimuth

• Stylus Distance and Overhang

We then do a critical listening test using our test records and our test system to ensure proper sonics.
