  • In essence a simplified ST40 MKIII, yet no reduction in quality, this is our best value integrated amplifier. Features include the excellent 6SN7 and KT88 valves for improved sound, and a headphone socket with excellent performance.


    Our simple bias circuit means that valve replacement of the same type requires no bias adjustment*. Yet retains the ability to use “tube roll” different valves (tubes), so the ST25 MK II is designed to use: 6L6, EL34, 6CA7, KT66, KT88, 6550.


    If you are new to valves the Stereo 25 MK II is an excellent starting point. With ample power, its affordable price and excellent power make it an ideal “starter” amplifier to find out what valves can do for your system.


    The inclusion of a dedicated headphone winding on the output transformers guarantees the best possible performance. Giving a closer intimacy than is possible that with solid state headphone amplifiers.



    Very “affordable” straightforward integrated amplifier based on the ST40 III with a first class headphone socket!

    Low maintenance and easy to use.
