As a longtime owner of a vintage Mac 2105 and a 2100, consider having a capable technician replace the old terminal strips with good quality modern posts that will accomodate spades or bananas. Yes, you will sacrifice the choice of 4,8 or 16 ohm taps, and will have to choose one of them, but it's worth it. Even if you can get the correct spades, connecting them with typically thicker, stiffer modern cables is a real pain. The small screws don't hold well, and sometimes just let go.
I made the change and love it. Sound quality was improved, and no more hassles. In my case, I always end up with 8 ohm speakers anyway.
