PotentiometerĬontrollerplatine 20V, the large IC’s were unsoldered and placed in PCB socketsįirst, the motor and the Technics IC's must be unsoldered from the old overall circuit board.
Possibility of setting the braking torque via an ext. on the controller board optimization of the power supply and Raising on 20V (from 12V). Connection to Controllerplatine via a multi-core cable. Adaptation of the actual engine to one smaller compact adapter board. He is incredibly well rested on improving existing drives.Įssentially, he turned the following screws: I would like to express my thanks to Björn from HH. The outer roundings were covered with 3mm aluminum”Lids”, which should give the player a symmetrical whole. The cable channels in the 2 Corian plate milled and the cover plate adapted to the plate and the stroboscope display. The outer shape would be taken from the underlying MPX plates, but an integration of the controls in the aluminum lid is also planned. Cover plate with electronics mountįor optical reasons, I opted for Corian decided in dark gray, that harmonizes very nicely with anodized aluminum and the planned tonearms. These are good prerequisites for the arm construction and a stable, toothed motor-tonearm structure. This has proven to be constructive, since the player is vibration-free in the end, and “insensitive to knocking” is. The feet have a diameter of 10 cm, consist of 3 Lay and close down with a Rubber buffering and M6 Spikes from. The overall chassis is made of 4 long M6 threaded rods, which under pull the chassis a certain amount – but not planned – Residual stress to lend. It had to be the outlets for the engine, and housing the electronics are taken into account.Ĭontrols (s.u.) found “in the feet” Shelter, so that a functionally and visually harmonious whole was created. I constructed the chassis from several arcs, that in the end 4 Layers of multiplex and two layers of Corian. To do this, the block had to be precisely matched to the screws of the motor and the mounting of the plate bearing. Adapter plate: the rubber buffer was replaced by stainless steel spacers – bombproof stand For this purpose, the unit consisting of drive and sensors is firmly soldered to the base board.Īs a mounting plate I have a massive one 10mm Alublock chosen, which should absorb some of the sound energy of the aluminum plate / motor unit and at the same time serve as a mount in the multiplex / Corian construction. 
The Technics motor is in the OEM lathe 3 Screws on the floor chassis and carries the electronics with it. 160 Euro dar, but plays tonally in the world of > 1000€ drives.
The project described below has a material value of approx. Gives Motor and plate are rather light, A compact design packed into a housing mass offered itself.Ī mix of materials made of multiplex floated me, Corian and brass / aluminum. The operation should be limited to the essentials, the player looks neat and not prone to interference. Otherwise, I was planning a version with one Swing arm boom, around all arms between 9 Inch short sleeve and 12 Inch to be able to assemble easily. Of the Torque increase I promised myself a lot….
In the “Birth idea” A good friend played me in the cards, who optimized the electronics and modified them to a 20V drive. ….butchered Technics Motr including electronicsĪs a direct drive motor it offers itself due to its Synchronism and his Kraft and its flat design as the core of a new turntable.

The engine from the Technics 1200 series is such an old stock, which was also installed in various OEM products. Sometimes it's just fun, that best of “Old stocks” to merge into a new whole and that Optimum to tickle out.
