  • What replacement transistors......can be used instead of the ZTX ones for a Spectrum48k? Or do i have to use like for like ?

    Are you talking about TR4 power supply transistor?
    If so, there is a good higher rated replacement: ztx651.

    Its still a ztx though, but is widely available.
