Owners manual

           

Modifications:

The power supply is very simple and can be improved.

Sound:

These series of audio components have only average sound quality, as all STK module equipped amps have.
Many manufacturers of audio equipment have used STK or alike IC modules in their audio gear, well known are:
Kenwood, Sansui, Akai, Marantz, Nad, Panasonic, Technics, JVC, Pioneer, Rotel, Denon, Quad, Sony, Yamaha, Bose, Philips and more.
This is not the same quality standard as other Luxman gear. It is from the era when the Luxman company was owned by Alpine.
