I have read many post, and think I may get my question answered here, I do hope anyway.
I just got a 1996 Hotsprings Sovereign brand and make of Spa from my Sister.

It has a 110V plug, I would like to convert it to 240V as I have a line already at the deck from my old Spa.

I have read that others where converting there brand of spas over and I am hoping that the Hotsprings is just as easy.
Thank You for any help,
Paul

Sorry, no can do.
Convertable Hot Spring Spas weren't introduced until 1997

ditto.
