Former distributor selling off his Bergmann Galder air-bearing turntable & Odin air-bearing, linear-tracking tonearm with vacuum hold-down. The package includes the (almost) silent air supply. Condition is used—9/10.
Here is one of the best thought-through turntable systems on the market. To play a record, all you do is remove the record weight and place the record on the platter, Press the 33 button, to turn on the motor. Put the record weight back on the spindle and voilá, you will see the record being sucked down, as the record rotates.
One of the key listening features is that the linear tracking tonearm sounds the same on track 1 as on track 6; – there is no tracking distortion.
The air-bearing platter & air-bearing tonearm delivers an incredibly quiet foundation underneath the music.
4-arm turntable, air-bearing design
Galder is Bergmann`s answer to the most universal turntable design. Galder accepts up to 4 tonearms.
- Radial- and linear tracking arms.
- Output for an air-bearing tonearm.
- The motorbase is separated from the plinth.
- Vacuum hold down, or clamp.
Advantage of using air bearings
The platter is centred by a steel spindle, running in a very frictionless, low noise and hard-wearing polymeric bearing material, and floats on a thin air cushion, which lowers the mechanical bearing noise to an absolute minimum- if any. (A traditional bearing solution, which keeps the platter centred AND supports the platter weight, makes a higher level of mechanical bearing noise, as the contact point between the spindle top and platter, generates a very high pressure – and hereby noise.)
By floating on an air cushion, the platter also gains the advantage of very good isolation from the surroundings, the same way as the known -and very expensive- air-supported shelves, used in many high-end audio systems.
Also, the speed stability benefits from the air-supported platter. The musical flow is really extraordinary – not necessarily measurable but audible.
Plinth
The plinth is made of one solid piece of cnc-machined die-cast aluminium, as well as the motorbase. Both parts have a powder-coated finish. The plinth is securely tightened to a 10mm aluminium bottom plate, which is standing on 3 adjustable feet.
The feet are an aluminium and ceramic ball construction. 3 upper and smaller ceramic balls configured in a triangle, is standing on top of one bigger lower ceramic ball. No matter the feet position, the 3 upper ceramic balls will always have perfect contact to the lower ceramic ball.
The motor base is standing on the aluminium bottom plate –but decoupled – and will always be aligned with the plinth, no matter the feet’ position.
On the back side of the plinth, the back panel is mounted. It consists of Ground, Air input, Vacuum input, output for an air-bearing tonearm, and air adjustment valves for the platter and tonearm.
Motorbase
The motorbase on Galder is equipped with a DC tacho motor. Communication between the tacho and the high-precision motor control electronic will keep the platter in a very accurate speed. We measured 0.0027% speed variation!
The power supply for the motor control electronic is built into in the air supply box, to keep high voltage distant from the interconnects delicate signal transmission. Connection is by a 5-meter shielded cable with LEMO connectors.
The air supply is remote-controlled from the motorbase. By pressing either 33 or 45 rpm, first press the air supply goes “ON”, and second press the platter starts to spin. When turning “OFF” at the selected speed, the air supply goes “OFF” automatically after 2 minutes. Very user-friendly and convenient.
Vacuum hold down
There are different ways to flatten a record and ensure that the record has good contact to the record mat/platter. A clamp covering the record label will only keep the centre of the record perfectly flattened. A metal ring, on the outer etch will only keep the outer part of the record flattened. The only way to flatten the record completely is by obtaining a vacuum between the record and the mat/platter – vacuum hold down. The vacuum hold invented by Bergmann Audio, is the most user-friendly system. The vacuum pump – which is in the air supply box – doesn’t need to be turned “OFF”, when changing the record. The user simply removes the vacuum clamp that is covering the centre spindle, and the vacuum is released, and the record can easily be changed while the platter is still spinning. After changing the record, put back the vacuum clamp, and the record is automatically flattened by the vacuum hold-down system.
Armboard
Galder accepts up to 4 tonearms – radial- and linear tracking tonearms. As standard, Galder comes with a main armboard, to fit almost any tonearm brand on the market – 9”, 10” and 12” tonearms.
We customize additional armboards for the tonearm brand you want to mount on the Galder turntable.
Air supply
The air supply has been the object of our greatest attention. The goal is to design a silent air supply, which could be placed in the listening room, and deliver an even, clean and dry air flow.
The pump is an oil-free, long-life unit, which does not require much maintenance.
The impulses from the pump are absorbed in an encapsulated reservoir. This results in an even airflow to the air bearing. The air supply is mounted with a filter, which prevents dust particles from entering the system. This filter is replaceable when necessary.
