    I'm a lot better mate, after a fairly radical but brief illness. That's why I was missing for a few weeks.

    Yes, that particular era of Tannoys sound wonderful, I'm working on a ten inch variant myself.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    Hard to say. I stick with Alcaps on older speakers where I can. They have no snob appeal but just work and don't seem to compromise sound.

    Definitely Plessey.

    The different sound could be down to different dielectric, are the supersound all polypropylene? As surmised I think the Plessey is likely Polyester.

    Dunno mate
    yes others have confirmed that they’re Plessey and that they’re still in tolerance so I’ll leave them alone now .
    Thanks for your input Alan

    I've got (or had) a few that look like that put away for my old B&W DM2s, long since sold. I was told they were NOS. Don't know the values.

    I can have a look but they'll be hard to find. I remember paying a few quid each, I guess they are now sought after for this very reason

    Futile to find them or futile to change them? I probably still have mine, I just need to empty every box on the cupboard and under the bed to find them! Then check their values, but Plessey rings a bell in remember looking them up at the time, they were taken over by Marconi or something.

    Fair enough I think I read they don't deteriorate like other types, I just wanted some spares in case they failed.

    Aluminium conductors, Copper leads but can be ordered in Silver, Polyprop dielectric I have always used Ansar cos they sound great & look Military grade & dont look out of place replacing the old Elcaps in vintage Crossovers.
