Leben CS300F


We have lusted after Leben amplifiers for years and now we are delighted to stock them!

Exceptional valve amplifiers, hand built in Japan to exacting standards and featuring very high quality components and valves.

And my! aren’t they pretty!  – call us for a demo.


The Leben CS-300F is an integrated amplifier with 15 watts of tube power – through the GE JAN-6197 valves previously used only for computers (JAN – Joint Army and Navy). They are low distortion and long life valve that Leben sourced many years ago and have been seeking the best circuit design to bring out the best performance in this clean tube. The driver circuit utilises a very high quality tube, the 17EW8 (Hi-Fi) produced specifically for hifi by a major Japanese electronics manufacturer. The result – a nice full sound and the bonus of a very high quality headphone output.
