    Default Leak Stereo 30 plus... advice please

    I need to test some tonearms and cartridges before I try to sell them.

    Ive bought a cheap technics T/t which will accept the arms, so I now need either a cheap phono stage or an integrated with built in phono.

    Before I do that, I’ve dug out an amp I’ve had for many years. A Leak stereo 30 plus.

    It came with a Rega 3 that I bought, and I heard it working then. But not since.

    However, when I go to set it up, it has some funny looking speaker connections. I need help.

    For each side, there is one connection with a larger hole than the other. The larger one has a kind of sideways E on it. This seems to accept a standard speaker lead.

    But the other hole is too small for a normal plug

    So... 2 questions.

    1) which hole does the red connector go to
    2) If I just forget about terminated leads, can I just jam bare wires in to these holes?

    Thanks

    Hi Brian,
    If you have established that these connectors are the speaker connectors, then as long as you put the speaker wires in both channels the same way around; ie; red to small hole, black to large hole etc, then the speakers should be in phase.
    Hope this helps.

    The smaller hole (3mm dia.) is what would normally be coloured RED, the large hole (4mm dia) is the BLACK. But as Anthony has said, it doesn't matter which way you connect the speaker cables as long as you are consistent.

    Anthony and Barry. Thanks for your help.

    We have lift off.

    Not via vinyl. That’s for another day, once I get around to setting up an arm

    But via Cd , the speakers are doing their thing. Sounds good. I should have tried this amp 8 years ago!!!

    It might be worth feeding the CD into the tape input of the 30 Plus, this avoids the preamp and tone controls, and gives a better sound than the other inputs. The volume control still works.

    That would be me. I've said rude things about them in the past.

    If you like vintage Brit amps, have you ever tried any of the early seventies P series amps from Cambridge Audio? They're worth a look.
    It is impossible for anything digital to sound analogue, because it isn't analogue!
