MINOS controller for Linn LP12 Sondek

Minos Turntable speed controller – Replacement for Linn Valhalla / Hercules / Lingo / Mose etc.

Most Linn turntables with Valhalla boards do not run at 33.33 rpm and have quite large variations in speed, some running as high as 34rpm. Upgrading to the Minos motor controller makes significant improvements to the listening sound stage, the sense of timing and rhythm of the track is far tighter.

The Minos controller is a replacement for non-speed sensing motor power supplies. Whilst not as feature rich as the Zeus, unlike most other power supplies parameters such motor drive voltage, motor phase and output frequency can be manually trimmed via software to minimise noise and vibration and platter rotation speed. The Minos has the same power saving features as the Zeus and of course electronic switching between 33.33 rpm and 45 rpm. It is supplied with an aluminium Linn style square switch with red and green LED’s.

The Minos board is designed, assembled and tested in the UK. Microprocessor controlled and fully CE approved.

• CE, UKCA approved
• Electronic switching between 33.3 rpm and 45 rpm
• High-efficiency low power consumption
• Upgradeable to a Zeus controller
• Highly accurate and pure sine wave frequency synthesis generated for 50Hz or 67.5Hz controlled to 0.001 Hz
• Control over motor parameters such as frequencies, phase angle, voltage amplitude via a serial interface. Adjusting these values enables the smoothest motor operation with minimum motor noise and vibration. Values may be written to EEPROM once optimum setup is achieved. The boards will ship with suggested default values but are fully configurable to suit your setup via a USB serial connection.
• Configurable Auto rotation on the application of main power
• Configurable low-power auto sleep timer when turntable idle.
• Fits on the original Linn Valhalla mounting.
• Ready for Linn Karousel bearing.
• Class A motor drive circuitry.
• Less heat is generated than the original Valhalla due to redesigned PSU section (no more burned-out resistors).
• Can be installed in Linn Axis – just wire the motor and existing power switch to the Minos (soldering required on Axis).
• Supply 110v-230v 50/60Hz.
• Works with 50Hz and 60Hz synchronous Linn/Premotec/Philips/Airpax 110V motors.
