    Hello, I've got an old pair of speakers, which are good sound and want to try and connect them to an amplifier with standard phono plugs. I might use them in the spare room or might even try and hook it up to my desktop.

    I have looked all over ebay for a modern phono plug cable with FEMALE old type 2 din plug for these speakers to plug into but can't find any.

    Does anybody know where I could get these, or use an intermediate lead of some sort please ?

    6 amp mains cable makes reasonable cost-effective speaker cable

    Sorry ne5, you're actually doing the wrong thing - speaker din plugs are meant to carry current, where Phono plugs are meant for signals with precious little current - which is why one wouldn't really want to mix and match.
    If you're amplifier has an audio output for speakers with phono plugs, it would be quite unusual, and certainly unconventional, for the phon spec is that of a complicated standard called RIAA - never normally having enough output to power speakers of any note.

    I’m going to make a few assumptions.

    First, it sounds like your speakers have a male RCA pin at the end of their speakers wires. Second, if that’s the case it is also probable that these wires are permanently connected to the speakers. They actually disappear into the back of the speaker box.

    If those two assumptions are correct and if you want to use the speakers with your present amp, you will probably have to cut the speaker wire close to the RCA pins. You can then attach whatever connections you prefer to the end of the speaker wires. You might decide to strip the the wires and attach them to a speaker outputs on the back of your amp.

    If I’m correct and you choose to go this route you must be very careful concerning the Ohms produced by those speaker and the combined total if you plan to run to sets of speakers. The total ohms your amp can push should be listed in the manual.

    Also, check the attached speaker wires. Are they very thin? Are they in good shape? You can’t ever be too sure.

    If they are in bad shape, it maybe possible to remove the back of the speaker box and check how the wires are attached. You might want to do away with the old wires and use a upgraded speaker wire.

    Finally, be sure you properly phase the speakers. Put the negative and positive ends of the speaker wires in their respective inputs.

    I hope this helps. Good luck.
