Picked up this old toy synth that was made in the 80s with the intention of teaching myself some stuff, but it came with no power cable. While I'm thinking of picking up an 8V adapter and Jerry-rigging the wires through the holes, I'd prefer to get something that doesn't require me to strip the wires, but if necessary I'll go ahead and snag an adapter and do that. Any help would be fantastic!
You could try spade or ring terminals on the ends of the wires, and then screw those in. I was wondering if banana plugs would fit in there, honestly.
