Black & white photo showing a Leben CS-600 tube amplifier with its lid removed, opening up to show two sets of tubes: Four 6CS7 tubes, two General Electric marked 'Tassa Radiofonica' & two 'RCA' ones for the driver/preamp stage and four driver tubes in addition to one 6DN3 damper tube.

In my current setup the driver tubes are Russian 80s productions from the Reflector brand / factory of the 6P3S-E type (semi-equivalent to the 5881/6L6).

The 6CS7 tubes are most likely produced 70s, and the driver tubes are from the 80s. Both sets aquired as New Old Stock (NOS).

Tubes are commonly referred to as 'valves' in British English.

Images of or related to the Leben CS-600 (and its siblings) designed by Mr. Taku Hyodo, commonly ranked one of the eight best amplifier designers in Japan.
