Don,
As long as I do gigs (probably >32 years now) I always took/take a complete set of spare-cables with me, 'hidden' somewhere in the car. One of each type :
Microphone-, power-, specials (e.g.Leslie) and speaker-cables.

Fran: As far as I remember Technics used to use the same type.... didn't they Scott ?
I too prefer the more solid (Euro?)connector but I can live with this one.
