Turntable »Bardo« – some technical information

History

After long years of interest, research and development, Helmut Brinkmann constructed the magnetic direct drive turntable »Oasis«. Since this project was well received by music lovers all over the world, we decided to release a second model that features the magnetic direct drive motor and is inspired by the design of our top-of-the-line models »Balance« and »LaGrange«.

Interesting details and upgrades

The picture shows the standard model »Bardo« with the magnetic motor drive. The »Bardo performance« features the metal cased power supply that is used for the »Balance« and »LaGrange« turntables instead of the standard power supply. The result is a more defined bass response and a wider room imaging.

The tonearm base of the »Bardo« can be rotated and fixed without play to allow a simple and precise tonearm adjustment for all tonearms between 9” and 12”. We drill the base according to the tonearm that the customer chooses.

The output sockets can be found on the back of the turntable, they can be equipped with RCA or XLR sockets, and it is also possible to install tonearms with DIN connectors or fixed cables.

The two possible speeds, 33 1/3 and 45 rpm, are selectable by a switch at the front of the turntable and can be fine adjusted via two screwdriver holes that are located next to the switch.

Magnetic drive

Tube power supply »RöNt II«

At first blush, it seems a crazy idea to use vacuum tubes for a low-voltage turntable power supply. So why do we do it? We found that the vacuum in the rectifier tubes not only isolates their plates from the cathodes, but also the power line from the drive circuitry.Because of this the »RöNt« works like a high class power line filter for our turntables. The purification of the mains noticeably improves the sound in terms of clarity, openness and spaciousness.

We changed the circuit to a single ended class A topography which gives a smoother and more transparent performance. The »RöNt II« delivers a stabilized output voltage of 24..25VDC, the output is short circuit proof.

The tube supply utilizes two high current low resistance pentodes (PL36) and one full wave rectifier (5AR4). All tubes are made for long life. Secondary AC voltage is rectified by the full wave rectifier and fed to both of the output pentodes via a line choke reducing even more mains noise. The output voltage is stabilized by controlling the output pentode stage.

For start up, the motor of our direct drive turntables needs about 450mA, the motor of our belt drive turntables needs about 150mA. Since we wanted to supply the benefits of our famous and unique »RöNt« for our direct drive models as well, we developed a new and more powerful circuit that meets the demands of all our models.

Tonearm »10.5«

The »10.5« is considered one of the best tonearms in the world and is used as a reference (and highly recommended) by magazines and reviewers alike throughout the world. The »10.5« is a true allaround tonearm. With a dynamic mass of 12 grams, it works well with any modern cartridge; and with 10.5'' length, it is still short enough for most turntables designed for 9-inch arms, yet also long enough for 12-inch arm bases. For optimum resonance control and high torsional stability, the »10.5« is made from aluminum and stainless steel; a high tech synthetic material is also used. For the same reasons, the headshell is nondetachable and the surface of the arm tube has also been treated with special anodizing. A double gimballed suspension, with precision ball bearings free of play, ensures precise and frictionless tracking. The vertical downforce and the dynamic mass can be adjusted over a wide range thanks to the split collar counterweight. Skating is compensated for without any contact by magnetic force. (Too bad you actually will hardly ever notice any of these efforts. Because simply put, the better a tone arm works, the more you'll hear what has been cut into the vinyl: music!)

The »10.5« features an infinitely variable Azimuth adjustment. A small clamping screw from under the arm tube holds the headshell in position. The headshell can be rotated by about ± 5° after untightening this screw. A precision-made plastic part mounted instead of the cartridge allows for aligning the headshell parallel to the platter or record surface. This plastic part has the same height like our EMT-ti cartridge and allows additionally for alignment of the arm height. If a cartridge has some deviation in azimuth, adjustment can be done by rotating the headshell in the desired direction to set the stylus of your cartridge vertical to the record surface.

The »Bardo« has a magnetic direct drive motor that was developed by Helmut Brinkmann and is produced in our factory. There is only one bearing for the motor and the platter, a circular magnet is mounted into the bearing of the platter and is concentrically driven into rotation via coils on the circuit board under the magnet. An electronic circuit drives the coils via two magnetic sensitive resistors that react to the magnetic fields into a highly constant and slow circular movement.

Many of the known direct drive turntables were constructed for studios and radio stations where it was necessary to have very quick start-up times of less than a second which was achieved with high torque motors that speed up and stop the motor very rapidly. This caused heavy cogging effects accompanied by high wow & flutter numbers. To avoid this, we worked long on a proprietary motor control that transfers just enough energy to the motor for it to remain at constant speed. The motor’s stator consists of four specially designed field coils, which are mounted concentrically with high precision around the platter bearing. Based on listening sessions we decided to forgo the typical 90-degree mounting angle in favor of a non-standard 22.5-degree roster, which, due to the magnetic fields overlapping, further reduced cogging. The motor’s rotor also acts as the sub-platter and carries a magnetic ring with eight poles on its underside. Inside the motor, the rpm of a speedometer disc is measured and turned into variable voltage that is fed into a control circuit where the rpm is compared to the reference voltage that is adjustable via the trim pots. A separate heater for the bearing, as included with the »Balance« and »LaGrange« bearings, is not necessary. The motor circuit is kept under current all the time, just the speed is switched to zero or 33 resp. 45. In this way, the bearing is kept warm by the quiescent current of the motor drive.
