FS: Leben CS600 integrated amplifier

Time for a change. For sale is my Leben CS600 integrated amplifier featuring gold knobs.

Picture of actual unit in my system here

Capable of using a wide variety of tubes, a quad of 6L6GC’s will come with the amp.

By switching two selectors inside of the cabinet, you can use either of 6L6GC or 6CA7 (EL34) , and LED indicators on the front panel will show you which tube is applied. Lots of KT tubes also work well (some require lid off/ use of spacers) - see here


Preamp-in terminals on the rear panel allow you to use CS-600 as a power amplifier. By switching a selector on the front panel, by-pass all the functions only excepting a Volume control.

Multi output impedance selector: 4/6/8/16 ohms.

Twin-triode tube 6CS7 for the first-stage amplification.

WBT type speaker terminals.

Heavy-duty output transformer for 50W grade amplifiers.
