Luxman CL-88 Tube Preamp
The CL-88, the Control Amplifier with line stage can supply power to the matching EQ-88 Moving Magnet Phono Stage for use with a moving coil cartridge. However, you will need to pair that up with the MT-88 Moving Coil Transformer. An outboard power supply, the OPEQ-88 is also available for use with this combination. The MQ-88 Stereo Amplifier have both fixed and variable inputs and can be used as integrated amplifier with a single input with a volume control in the front panel.
Luxman's stereo vacuum tube control amplifier, with an ALPS precision brass, four gang volume control, featuring an in-built mute function. By touching the centre of the volume control, the sound mutes at once. Signal switching is performed by a golden switch immersed in a nitrogen container, located near the input terminals in order to maintain a low S/N Ratio. Also available, the MT-88 moving coil step-up transformer.
Kappa Alloy RCA Jacks
This custom RCA socket was developed for the universal music player DU-80, it is a unique blend of copper and brass, chosen for its conductance properties, This new kappa alloy material is used for both the RCA input/output terminals, holds a secure connection and ensures that any sound quality deterioration is kept to a minimum.
The volume control on the L-509u is a solid brass, four gang ALPs potentiometer, it's too heavy to be motorized, hence the lack of a remote control, it does however provide a linear attenuation and gain throughout the range, holding both channels perfectly in balance even at low amplitude.
Throughout the 88 vacuum tube series, a 15mm thick top panel and solid brass supports are used as a suspension structure. By cleverly hanging the electronics from the top plate, the mechanical vibrations are isolated from the delicate low level music signal. The gradation cast-iron legs are provided to protect the tiny delicate sound signals from unwanted vibration.
