What speaker cables for vintage equipment

I would recommend highly that you use ordinary 14awg bare copper wire and twist it around the screw terminals. Now talk about nostalgia.Its allot cheaper and will sound great at less then a dollar a ft.

Thanks so far for the suggestions. Cutting off the existing spades is not an option, I need the cables for another amp that works well with these.
Does anyone know of a company that makes a spade or ? that will fit the
barrier strips and that will allow a regular size spade to connect to it ( the smaller spade).
That would be my ideal solution.

I believe this will do the trick. I use one with my MC275 and it allows you to use cables of your choice. Maybe a bit pricy but a very high quality construction piece.

Home Depot is your best bet.

I think Lat International sells cables with spades suitable for older equipment.
