    Is this instead of, or as well as, your wish for a vintage British integrated?

    There was never an STA 25 Mk.I as such, but there was an MA25 Mk.I, a single channel amplifier. There was a Mk.II version of the MA25, where the phase splitter used an ECF82 in place of an ECC83. The only true STA25 was the designated STA25 Mk III and this (along with its smaller sister, the STA15 Mk.III) are excellent amplifiers.

    I would have no hesitation in using one to drive Tannoys.

    Ah, that explains why it says STA 25 Series 3, not Mark 3. Interesting to see the Leak Stereo 50 bunched together with the Radford.
