Thanks everyone. Learned a lot. In the end figured out that I had some combined banana plugs for the speakers that allow to screw the spade into the top of the connector. The unit is brass and from a company called Mitchell. I bought them 15 years ago, but they seem OK. Thanks everyone.
Spade termination on speaker
I just purchased a new speaker cable (well over due). The old cables had banana that fitted into the speaker banana termination. The new cables are Coincident and have big spades at the end. I need to upgrade the termination on my speaker to put these spades in. Any one knows of a good termination to buy to put on my speaker? Where do I buy it from?
